Critical raw materials revisited

• Possibility (or not) of substitution
• Irreplaceable functionality
• Potential supply risks

Demand is increasing for critical metals due to:

• Economic growth of developing countries
• Emergence of new technologies and products

Access to raw materials at competitive prices has become essential to the functioning of all industrialized economies. As we move forward developing and developed countries will, with their:

• Massive population booms
• Infrastructure build out and urbanization plans
• Modernization programs for existing, tired and worn out      infrastructure

Continue to place extraordinary demands on our ability to access and distribute the planets natural resources.

Threats to access and distribution of these commodities could include:

• Political instability of supplier countries
• The manipulation of supplies
• The competition over supplies
• Attacks on supply infrastructure
• Accidents and natural disasters
• Climate change

Accessing a sustainable, and secure, supply of raw materials is going to become the number one priority for all countries. Increasingly we are going to see countries ensuring their own industries have first rights of access to internally produced commodities and they will look for such privileged access from other countries.

Numerous countries are taking steps to safeguard their own supply by:

• Stopping or slowing the export of natural resources
• Shutting down traditional supply markets
• Buying companies for their deposits
• Project finance tied to off take agreements

In this article I am going to take a look at three reports covering what the US and Europe consider critical or strategic minerals and materials.

In its first Critical Materials Strategy, the U.S. Department of Energy (DOE) focused on materials used in four clean energy technologies:

• wind turbines – permanent magnets
• electric vehicles – permanent magnets & advanced      batteries
• solar cells – thin film semi conductors
• energy efficient lighting – phosphors

The DOE says they selected these particular components for two reasons:

• Deployment of the clean energy technologies that use      them is projected to increase, perhaps significantly, in the short, medium      and long term
• Each uses significant quantities of rare earth metals      or other key materials

In its report the DOE provided data for nine rare earth elements: yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, terbium and dysprosium as well as indium, gallium, tellurium, cobalt and lithium.

Five of the rare earth metals – dysprosium, neodymium, terbium, europium and yttrium – as well as indium, were assessed as most critical in the short term. The DOE defines “criticality” as a measure that combines importance to the clean energy economy and risk of supply disruption.

In a follow up to its earlier report the U.S. Department of Energy, Dec. 2011 – Critical Materials Strategy, examined the role that rare earth metalsand other key materials play in clean energy technologies such as wind turbines, electric vehicles, solar cells and energy-efficient lighting.

The five rare earth metals – dysprosium, neodymium, terbium, europium and yttrium are considered to be the most critical of the elements considered in the report.

Securing Materials for Emerging Technologies

A Report by the APS Panel on Public Affairs and the Materials Research Society coined the term “energy-critical element” (ECE) to describe a class of chemical elements that currently appear critical to one or more new, energy related technologies.

“Energy-related systems are typically materials intensive. As new technologies are widely deployed, significant quantities of the elements required to manufacture them will be needed. However, many of these unfamiliar elements are not presently mined, refined, or traded in large quantities, and, as a result, their availability might be constrained by many complex factors. A shortage of these energy-critical elements (ECEs) could significantly inhibit the adoption of otherwise game-changing energy technologies. This, in turn, would limit the competitiveness of U.S. industries and the domestic scientific enterprise and, eventually, diminish the quality of life in the United States.”

According to the APS and MRS report several factors can contribute to limiting the domestic availability of an ECE:

• The element may not be abundant in the earth’s crust or      might not be concentrated by geological processes
• An element might only occur in a few economic deposits      worldwide, production might be dominated by and, therefore, subject to      manipulation by one or more countries – the United States already relies      on other countries for more than 90% of most of the ECEs identified in the      report
• Many ECEs have, up to this point, been produced in      relatively small quantities as by-products of primary metals mining and      refining. Joint production complicates attempts to ramp up output by a      large factor.
• Because they are relatively scarce, extraction of ECEs      often involves processing large amounts of material, sometimes in ways      that do unacceptable environmental damage
• The time required for production and utilization to      adapt to fluctuations in price and availability of ECEs is long, making      planning and investment difficult

This report was limited to elements that have the potential for major impact on energy systems and for which a significantly increased demand might strain supply, causing price increases or unavailability, thereby discouraging the use of some new technologies.

The focus of the report was on energy technologies with the potential for large-scale deployment so the elements they listed are energy critical:

• Gallium, germanium, indium, selenium, silver, and      tellurium – employed in advanced photovoltaic solar cells, especially thin      film photovoltaics.
• Dysprosium, neodymium, praseodymium, samarium and      cobalt – used in high-strength permanent magnets for many energy related      applications, such as wind turbines and hybrid automobiles.
• Gadolinium (most REEs made this list) for its unusual      paramagnetic qualities and europium and terbium for their role in managing      the color of fluorescent lighting. Yttrium, another REE, is an important      ingredient in energy-efficient solid-state lighting.
• Lithium and lanthanum, used in high performance      batteries.
• Helium, required in cryogenics, energy research,      advanced nuclear reactor designs, and manufacturing in the energy sector.
• Platinum, palladium, and other PGEs, used as catalysts      in fuel cells that may find wide applications in transportation. Cerium, a      REE, is also used as an auto-emissions catalyst.

The third report I looked at, “Critical Raw Materials for the EU” listed 14 raw materials which are  deemed critical to the European Union (EU): antimony, beryllium, cobalt, fluorspar, gallium, germanium, graphite, indium, magnesium, niobium, platinum group metals, rare earths, tantalum and tungsten.

“Raw materials are an essential part of both high tech products and every-day consumer products, such as mobile phones, thin layer photovoltaics, Lithium-ion batteries, fibre optic cable, synthetic fuels, among others. But their availability is increasingly under pressure according to a report published today by an expert group chaired by the European Commission. In this first ever overview on the state of access to raw materials in the EU, the experts label a selection of 14 raw materials as “critical” out of 41 minerals and metals analyzed. The growing demand for raw materials is driven by the growth of developing economies and new emerging technologies.”

For the critical raw materials, their high supply risk is mainly due to the fact that a high share of the worldwide production mainly comes from a handful of countries, for example:

• China – Rare Earths Elements      (REE)
• Russia, South Africa – Platinum Group Elements (PGE)
• Democratic Republic of Congo – Cobalt

Taking all the metals, from all three lists, gives us: 

 

Antimony beryllium Cerium Cobalt Dysprosium Europium fluorspar Gadolinium Gallium Germanium Graphite

Helium Indium Lanthanum Lithium Magnesium Neodymium Niobium Palladium Platinum Praseodymium

Rhenium Samarium Selenium Silver Tantalum Tellurium Terbium tungsten Yttrium

The key issues in regards to critical metals are:

• Finite resources
• Chinese market dominance in many sectors
• Long lead times for mine development
• Resource nationalism/country risk
• High project development cost
• Relentless demand for high tech consumer products
• Ongoing material use research
• Low substitutability
• Environmental crackdowns
• Low recycling rates
• Lack of intellectual knowledge and operational      expertise in the west

Conclusion

Critical materials should be on every investors radar screens. Are they on yours?
