NEO-COLONIALISM.

government’s position that the big deposits, including those in the precious
metals field, should be developed only by Russian companies” [Putin
Moves to Limit Foreign Investment – The Epoch Times; May 13 – 19, 2005].
“The need to nationalize
companies such as Inco has been recognized for many
years. The disaster which has now befallen Sudbury as a result of Inco’s failure to build downstream processing facilities or
to reinvest its profits in the local community underlies why public control of
our mineral resources is so vital” [Daniel

“The most telling feature
of the trade deal is the way it restricts Canada’s ability to modify its
industrial structure, thus limiting Canadian governments ability to manage the
economy strictly in Canada’s national interest” [Marc Gold and David Leyton-Brown

about becoming a satellite of the United States, it might be expected that this
country would take an active part in assisting the developing countries to
achieve the best bargain with prospective investors” [Peyton

The staple theory is considered to be
In
exposing their industries to the global business cycle, Canadian’s have paid a
high price [Ibid]. “Whereas the
earlier staple trades demanded commercial capital and investment in
infrastructure, particularly in transportation, the new staples of the
twentieth century…required enormous investments in fixed capital without
proportionate demands for development-supporting investments in infrastructure
for forward and final demand linkages. Large backward linkages did exist, but
for the most part these were either captured by foreign investment, or were
manifested in the initial construction boom. In this manner,
Flashback…
“Nickel
is prominent on the United States Department of the Interior list of 13 basic
raw materials required by an industrial society…The oil crisis of 1973-74 has
made obvious to all a truth which American policy makers have long understood;
secure supplies of raw materials at reasonable prices are the lifeblood of any
industrial nation… Security of basic materials, when both the outcome of wars
and the ability to maintain the uneasy balance of terror between wars are
closely related to economic strength and performance,
is a paramount objective…Within the general scheme of raw material supplies,
nickel has a special place. The U.S. Defence
Department warned in 1945 that nickel comes
closest to being a true ‘war metal’. It deserves the first priority among
metals receiving conservation attention. Since the start of the Korean War, nickel
has remained the world’s most critical material; this condition is likely to
continue for some time…The properties that make nickel such a useful and
strategic metal are its strength, hardness, ductility, and resistance to
corrosion, plus the ability to retain these features at extremely high and low
temperatures. It imparts these same benefits to other metals… when combined
with them in alloys…American industry has long experience in attempting to find
substitutes, but nickel consumption continues to grow rapidly. The growth in
demand continues despite rising prices…The reason for this strong demand, not
only in the
“Commercial
production of nickel in Canada, the world’s leading producer for nearly 70
years, was begun for military purposes…The U.S. navy moved quickly to pursue
the technological advantage nickel seemed to offer. Nickel steel passed the
artillery punishment tests with flying colours and
was judged the most wonderful armour plate ever made…the Canadian Copper Company made
its first sale in 1891 to the United States Navy, and the new industry was on
its way…expansion of nickel production was based primarily on meeting the
demand of the various national military establishments… During the 1960’s the
increasing civilian uses of more than 3000 nickel alloys competed with the
military requirements of the Vietnam war to encourage
a further strong growth in productive capacity.
“Space
and military technology and all related civilian production dealing with
intense stress and heat require extremely high-performance materials in large
quantities, as for example in the large and powerful jet engines of the
aircraft industry. The change in the scale of demand is indicated by the
changing nickel requirements of that industry: a four engine piston driven
plane required only about 125 pounds of nickel; a commercial four engine jet
requires 4,000 pounds; the Boeing 747 jumbo uses 11,000 pounds; and the
supersonic transports, if their day ever comes, will each need 18,000 pounds of
nickel. The same trend appears in any productive activity where the power, size
and speed of machinery is increasing.
“Another
special feature of nickel, its non-corroding quality, spreads the demand for
nickel to other high-technology growth industries. The petroleum industry in
the capitalist world now uses 64 million pounds of nickel annually, mainly in
refinery process equipment. The new nuclear power plants require large amounts
of nickel alloy tubing in their heat exchanger systems, and a similar need for
miles of nickel alloy tubing arises from the desalinization plants which will
be needed to increase fresh water supplies. The same is true
of pollution control systems for the treatment and disposal of industrial
wastes” [John Deverell and the Latin American Working Group, 1975; Falconbridge: Portrait Of A Canadian Mining Multinational, James Lorimer and Company, Publishers (

emergence of large scale ventures in the mining of lateritic

How history repeats itself….
Titanium
is not only about half as dense as ferrous and nickel-based metals, it
also possesses an exceptionally high strength to weight ratio. This
means that when equipment costs are calculated on a per unit area of measure
basis, rather than per pound, the differential cost of material required
narrows dramatically. In other words, owing to its superior strength, about
half as much titanium is required to do the same job. Looked at in another way,
the same weight of titanium will go twice as far. It also offers lifecycle cost
advantages while providing initial cost advantages [http://www.timet.com/industrial.html].
For the sake of brevity, this write-up
shall focus on (I) zircon and (II) rutile,
the ores from which the multinational expects to earn 80% of its revenues [www.tiomin.com].
(I) Zircon.
This is reputed
to be the oldest mineral on earth. It derives its name from the Arabic /Persian
word zarqun,
which means gold colour.
According to rock samples obtained from previous Apollo space missions, zircon is also found in abundant quantities
on the moon [http://en.wikipedia.org/wiki/Zirconium].
1st IMPORTANT NOTE: “Zircon is extracted as a co-product or
by-product of titanium minerals…The global demand for zirconium materials
increased in 2002. Growth was expected to increase by 3% to 5% per year during
the next few years, and new deposits are expected to come online…further
exploration and development efforts are underway in Australia, Canada, India,
Kenya, South Africa, and the United States” [Zirconium and Hafnium – By James B. Hedrick (U.S Geological Survey
Minerals Yearbook – 2002)]. Another report has stated that “there is a very
real risk that demand for zircon could soon be substantially greater than
global supply…the shortfall could be more than 100,000t in 2005 and some
industry observers believe that even if all the planned mineral sands projects
come into production over the next ten years, demand will outstrip supply. If zircon production does not increase to
meet the expanding demand, prices will continue to rise…the last three years
have shown a degree of concentration of corporate control of zircon
production…Four corporate groups now effectively control about three quarters
of the world’s zircon supply...Prices for zircon sand have been rising since
1999. Since the beginning of 2003 ceramic grade zircon sand prices have
increased by nearly 25%...Over the same period the price for opacifier-grade milled zircon increased…which reflects
strong competition between zircon milling companies in the west and their need
to remain competitive in an industry facing a strong challenge from China” [Zircon Prices continue to rise as demand
exceeds supply – www.roskill.com/reports/zirconium].
2nd IMPORTANT NOTE: Zircon is the primary ore source of
zirconium metal and hafnium, which both have critical uses, as we shall soon
see.
Applications.
N.B: The
only application that Tiomin mentions, with respect to zircon, is that it is
used in the jewellery
industry. Here are a
few others that may be worth
considering…
(1) The Nuclear Industry.
Note: The information below is only for
‘illustrative’ purposes, regarding the
significance
of zircon.
Zirconium metal - Owing to its remarkably
low-absorption cross-section for neutrons, zirconium metal is ideal for nuclear
energy uses, such as cladding nuclear fuel elements [http://en.wikipedia.org/wiki/Zirconium]. Today’s commercial
reactors may use as much as a half-million linear feet of zirconium alloy
tubing. (As a matter of fact, more than 90% of the metal is utilized in nuclear
power generation). A good example is the CANDUTM
(“
Hafnium – About half of all hafnium metal is produced as a byproduct of
zirconium refinement. The two are usually difficult to separate owing to their
almost identical chemistry. Hafnium, however, has an extremely high absorption
cross-section for neutrons (600 times that of zirconium!). It is therefore a
very vital component of reactor ‘shutdown systems’, playing a critical role in
the event of emergencies such as reactor overpower, loss of reactor regulation,
or impairment of fuel cooling [Maple
Facilities For National Nuclear Programs – R.F Lidstone
et al (Atomic Energy of Canada Limited). See also Advanced Test Reactor – http://nuclear.inel.gov/facilities/atr.shtml
and Maple Research Reactor Beam-Tube
Performance – A.G Lee et al (Atomic Energy of Canada Limited)].
(a) Electricity Generation.
As the energy
marketplace evolves, the challenge is to respond competitively to new economic
expectations for low-cost, high-quality nuclear generation. Advances in
technology make the economics of nuclear power more attractive, and they may
become even more so as fuel prices continue rising [“Nuclear Power for the 21st Century” – International
Ministerial Conference (
However, “the
prospects for using nuclear energy have been hampered because the large size of
nuclear plants makes them unsuitable for lower capacity electricity grids. For
this reason the IAEA has maintained a focus on the potential for innovative
small and medium sized reactor design, and a few projects are moving toward
implementation” [www.aecl.ca]. Atomic Energy
of Canada Limited has developed the ACRTM
(Advanced CANDU Reactor), an
innovative next-generation CANDU
product to not only meet these requirements, but also the demands of
electricity companies around the world [related ref: Atomic Energy of Canada Limited: The Crown Corporation as Strategist in
an Entrepreneurial, Global-Scale Industry – Lermer
George, Canadian Government Publishing Centre (Ottawa, 1987)].
In recent news,
“the Canadian Prime Minister, Paul Martin and Chinese Premier Wen Jiabo, witnessed the signing
of Memorandum of Understanding (MOU)…that will…establish a framework for
collaboration on research and development programs, projects and activities
aimed at furthering a basic understanding of nuclear energy and its
applications, and improving cost and safety of nuclear energy systems…The CANDU 6 nuclear reactor has been one of
the most successful power reactor designs providing cost effective, clean and
reliable electricity to countries on four continents” [Canada and China Strengthen Cooperation in Nuclear Energy – News
Releases (Atomic Energy of Canada Limited, www.aecl.ca), 20th
January 2005]. AECL recently

Research and Design Institute). “This strategic partnership agreement
provides a platform to promise the localization and further development of
CANDU technology in
(b) Nuclear Medicine.
“The health
care industry continues to discover innovative ways to improve the lives of
people globally. Medical research using isotope based technologies have enabled
scientists; physicians and clinicians to research, develop and apply advanced
therapies. Isotopes have enabled research into the functioning of the human
body, evaluation of organs that are critical to normal human development, and
the ability to apply leading-edge therapies…The radiopharmaceutical industry
continues to develop treatment that relies on medical isotopes for accurate
diagnosis, cancer therapy and pain control. Advanced techniques such as brachytherapy and radioactive implants have proven to be
effective therapies. Recent explorations using monoclonal antibodies
radio-labeled with isotopes – the “magic
bullet” – have demonstrated the value
of continued medical research using isotope-based technologies.
“Molybdenum-99
(Mo-99) is the backbone of the nuclear medicine industry. It is used to make
Mo-99/Technetium-99m (Tc-99m) generators, which are used in most nuclear
medicine departments around the world. Tc-99m is, by far, the most widely used
radioisotope in nuclear medicine. It is estimated that 50,000 people worldwide
benefit daily from the use of this isotope” [A Conversion Development Program To LEU Targets For Medical Isotope

(c) Producing hydrogen for
transportation fuels.
“The goal of
the Nuclear Hydrogen Initiative is to demonstrate the economic commercial-scale
production of hydrogen using nuclear energy by 2015, and thereby make available
a large-scale, emission free, domestic hydrogen production capability to fuel
the approaching hydrogen economy…nuclear energy can produce hydrogen in very
large quantities consistently over long periods of time without emitting
greenhouse gases or other harmful air emissions. The…hydrogen fuel initiative
is a new research and development initiative focused on hydrogen to reverse
America’s growing dependence on foreign oil and expand the availability of
clean, abundant energy” [Nuclear Hydrogen
Initiative: Office of Nuclear Energy, Science and Technology, U.S Department of
Energy – March 2003. See also Nuclear

September 2004. Related references: New Nuclear Power Plants Are Vital to U.S
Energy Security, NEI tells Congress – The Nuclear Institute (NEI), www.nei.org and President
Bush Calls for Expanding Nuclear Energy in State of the Union Address – (Ibid)]. Canadian experts have proposed
building one CANDU reactor every
year, for the next 20 years, in order to supply an estimated 13 million
hydrogen-powered vehicles. Some authorities have even predicted that “the
energy demand for hydrogen production could exceed that now used for
electricity production” [The Hydrogen

the picture. In 1993, the International Atomic Energy Agency (IAEA) concluded
that using nuclear energy to desalinate water could be carried out safely and
reliably, without any technical difficulties” [Nuclear and Alternative Technologies – Atomic Energy of Canada

Nuclear
facilities can also be used in underlying research into nuclear science and

Neutron Facility (CNF) research
reactor is expected to ultimately improve everyday Canadian products including
automobiles, airplanes, pharmaceuticals, food, biomaterials, electronics, and
computing devices. Australia, Germany, China, Holland, Japan, Thailand, and
Egypt have also “identified the requirement of advanced materials research
facilities in the twenty-first century and are already constructing, or
planning to construct new research reactors” [Ibid].
N.B: Nuclear power proponents have claimed
that it reduced the global production and release of some 500 million metric
tones of carbon dioxide in 2002. The aforementioned proposal by Canadian
authorities, to build one CANDU reactor
every year for the next 20 years, is expected to help reduce carbon dioxide
emissions by 120 million metric tonnes per year [www.aecl.ca]. About 150 companies
support the Canadian Nuclear program, with most of the revenues flowing to
private industry [CANDU Nuclear Power
Technology – www.nuclearfaq.ca].
(2) Fuel Cells.
(a) The Solid Oxide Fuel Cell (SOFC).
This is an electrochemical device that converts the chemical energy in fuels (such as hydrogen, methane, butane or even gasoline and diesel) into electrical energy by exploiting the natural tendency of oxygen and hydrogen to react. By controlling the means by which such a reaction occurs, as well as directing the reaction through a device, it is possible to harvest the energy given off by the reaction [http://www.csa.com/hottopics/Fuecel/oview.html].
“Engineers and environmentalists have long dreamed of being able to obtain the benefits of clean electric power without pollution-producing engines or heavy batteries. Solar panels and wind farms are familiar images of alternative energy technologies. While they are effective sources of electrical energy, there are problems with the stability of their energy source as, for example, on a cloudy or windless day. Their applications are somewhat limited due to lack of portability; a windmill is not much help to the power plant of a diesel truck, a solar panel cannot provide power at night, etc.
“In 1962 a revolution in energy research occurred. Scientists at Westinghouse Electric Corporation (now Siemens Westinghouse) demonstrated for the first time the feasibility of extracting electricity from a device they called a solid electrolyte fuel cell…Since then there has been an intense research and development effort to develop the alternative energy technology known as fuel cells. Now, as energy issues are at the forefront of current events, fuel cell technology is ripening and on the verge of being ready for large scale commercial implementation.
“Much development has focused on solid oxide fuel cells because they are able to convert a wide variety of fuels and because they do so with such high efficiency (40-60% unassisted, up to 70% in pressurized hybrid system) compared to engines and modern thermal power plants (30-40% efficient)…SOFC technology dominates competing fuel cell technologies because of the ability of SOFCs to use currently available fossil fuels, thus reducing operating costs. Other fuel cell technologies (e.g. molten carbonate, polymer electrolyte, phosphoric acid and alkali) require hydrogen as their fuel. Widespread use of such fuel cells would require a network of hydrogen suppliers, similar to our familiar gas stations.
“High efficiency and fuel adaptability are not the only advantages of solid oxide fuel cells. SOFCs are attractive as energy sources because they are clean, reliable, and almost entirely nonpolluting. Because there are no moving parts and the cells are therefore vibration-free, the noise pollution associated with power generation is also eliminated.
“Although the operating concept of SOFCs is rather simple, the selection of materials for the individual components presents enormous challenges. Each material must have the electrical properties required to perform its function in the cell. There must be enough chemical and structural stability to endure fabrication and operation at high temperatures. The fuel cell needs to run at high temperatures in order to achieve sufficiently high current densities and power output; operation at up to 1000 C is possible using the most common electrolyte material, yttria-stabilized zirconia (YSZ).
“The
“There seems, therefore, to be little doubt that SOFC technology will be implemented. Analysts expect that the overall market for fuel cell technology could reach $95 billion by the year 2010…The market share that will belong to SOFCs is unclear but will surely be significant, as SOFCs are targeted for use in three energy applications: stationary energy sources, transportation, and military applications.
“Stationary installations would be the primary or auxiliary power sources
for such facilities as homes, office buildings, industrial sites, ports, and
military installations. They are well suited for mini-power-grid applications
at places like universities and military bases…worldwide demand for electricity
is expected to double in the next 20 years. SOFC technology is ideal for such
an expansion, since much of the anticipated demand is expected to come from
growing economies with minimal infrastructure. SOFCs
can be positioned on-site, even in remote areas; on-site location makes it
possible to match power generation to the electrical demands of the
site…Siemens Westinghouse has tested several prototype tubular systems, with
excellent results. A plant in the
Several hundred residential
stationary power units utilizing SOFCs are presently
being tested in
“In the transportation sector, SOFCs are likely to
find applications in both trucks and automobiles. In diesel trucks, they will
probably be used as auxiliary power units to run electrical systems like air
conditioning and on-board electronics. Such units would preclude the need to
leave diesel trucks running at rest stops, thereby leading to a savings in
diesel fuel expenditures and a significant reduction in both diesel exhaust and
truck noise. Meanwhile, automobile manufacturers have invested at least $4.5
billion in fuel cell research (not all SOFC)…There are an estimated 600 million
vehicles worldwide, 75% of which are personal automobiles, and the number is
expected to grow by 30% in the next 10 years…With more stringent environmental
restrictions in the United States and European Union, automobile manufacturers
are under growing time pressure to bring non-polluting cars to the marketplace.
SOFCs are
attractive prospects because of their ability to use readily available,
inexpensive fuels” [http://www.csa.com/hottopics/Fuecel/oview.html]. In

(b) Micro Fuel cells.
“About 400 million
portable devices such as cell phones, laptops, and digital cameras are sold
each year to the huge and growing market of 1.4 billion users – a $5 billion
market that is expected to reach 2 billion users by 2007. The trend is to
continue adding more energy thirsty features to these devices, from color
screens to memory, and toward multipurpose devices like cell phones that double
as digital cameras. Current battery technologies can’t satisfy this energy
demand. Devices are also getting smaller making it doubly challenging to find
room for a battery” [Partner

are expected to solve this problem in the future.
(3) Other applications in the transportation
industry.
Zirconium compounds also provide catalytic functionality by
reacting with noxious gases such as carbon monoxide and nitrogen oxide in
automobile catalytic converters (and power generating equipment), to prevent
environmental pollution arising from burning gasoline and coal [What are Nanomaterials?

results in increased performance coupled with higher temperature
stability, a key feature for the newer generations of automobile catalysts [AMR Technologies: Zirconium Markets &
Applications – www.amr-ltd.com/products/zirconium_markets.html].
“The market for catalytic converters is growing as emission standards are
introduced in developing sectors of the world, and are continuously becoming
stringent in developed areas. A major growth driver for the industry is the new
demand from developing countries, such as
Automobile engines waste considerable amounts of gasoline. This is because conventional spark plugs are not designed to burn gasoline completely and efficiently. This problem is compounded by defective or worn-out, spark plug electrodes. Nanocrystalline ceramics such as zirconia, which has even been rendered “superplastic”, are stronger, harder, and much more wear-resistant / erosion-resistant. These ceramics can be pressed and sintered into various shapes at significantly low temperatures, whereas it would be almost impossible, to press and sinter conventional ceramics even at high temperatures [What are Nanomaterials? – www.nanomat.com/nanoint.htm].
Automobiles also waste significant amounts of energy by losing the thermal energy generated by the engine, particularly in the case of diesel engines. Hence, engine cylinders (liners) are currently being coated with nanocrystalline ceramics, so that they retain heat much more efficiently, which results in complete and efficient combustion of fuel [Ibid]. Thermal barrier usage in the IGT (industrial gas turbine) market alone is expected to grow tremendously over the coming years [AMR Technologies: Zirconium Markets & Applications – www.amr-ltd.com/products/zirconium_markets.html].
High-sensitivity sensors – Sensors employ their sensitivity to the changes in various parameters they are designed to measure. The measured parameters include electrical resistivity, chemical activity, magnetic permeability, thermal conductivity, and capacitance. All of these parameters depend greatly on the microstructure (grain size) of the materials employed in the sensors. A change in the sensor’s environment is manifested by the sensor material’s chemical, physical, or mechanical characteristics, which is exploited for detection. It follows, therefore, that sensors made of nanocrystalline materials such as zirconia, are extremely sensitive to changes in their environment. Typical applications for such sensors are smoke detectors, ice detectors on aircraft wings, automobile engine performance sensors (e.g controlling air to fuel combustion ratios) etc [What are Nanomaterials? – www.nanomat.com/nanoint.htm].

be made smaller, allowing a greater degree of articulation. The ability to be
polished to a high surface finish also allows a low friction joint to be
manufactured for articulating joints such as the hip. Bioceramics
such as Partially Stabilized Zirconia (PSZ) possess,
among other qualities, high flexural strength, fracture toughness and excellent
reliability. Partially stabilized zirconia femoral
heads make up about 25% of the total number of operations per year in Europe,
and 8% of the hip implant procedures in
Superconducting magnets containing zirconium also greatly
enhance the ability of magnetic resonance imaging (MRI) scanners and other
non-destructive examination devices, to sense minute changes in magnetic fields
