Thorium: Rare Earth Liability or Asset?

By Michael Montgomery

The production of rare earth oxides comes attached with a major problem: radioactive waste. The mining of the rare earths and the processing of the various elements produces large amounts of thorium as a byproduct. This material is radioactive and dangerous to human health. In China, lax environmental laws have allowed the country to build a monopoly in the market. However, now the country is looking to mitigate environmental damage from the production of rare earths, shutting down small mining operations, and raising environmental standards. This has had a dramatic effect on the price of these elements, which is why western companies are looking to produce on their deposits. One such company, Lynas Corporation (ASX:LYC) is building a processing plant in Malaysia that is coming under fire as concerns about the disposal of thorium and the effects on the local population mount. There is a possibility that this liability could become a resource of rare earth mining companies, as thorium can be used as fuel for nuclear power.
“The 800-pound gorilla in every rare-earth venture’s room, was the radioactive thorium- and/or uranium-bearing waste that will be generated by the extraction, separation, and refining operations,” stated rare earth expert, Jack Lifton. Article published here
