The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.
High Yield, Economical, Large Scale Production of Marketable Rare Earth Element Products from Coal Mining Refuse — Equinox Chemicals LLC (Albany, GA) and project partners will conduct laboratory testing and prepare a technical design for a pilot plant to produce salable REEs.They will use by-products from an existing eastern Kentucky coal preparation plant as their source of REEs.
The Mountain Pass Rare Earth Mine is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range, just north of the unincorporated community of Mountain Pass, California, United States.The mine once supplied most of the world's rare-earth elements. Today, it is owned by MP Materials, and is the country's only rare earth mining and processing facility.
Regulation of environmental and health impacts in the rare earth element industry. Rare Earth Element (REE) mining, processing and exploitation are large scale industries that use a wide range of stone substances and generate significant quantities of waste.
Expansion of mining operations and changes to milling and processing operations may require environmental review and additional permitting for these active mining operations. In addition to rare earth production from current mining sites, it could become
TRU Group developed the mixed rare earth stone process and individual RE separation method (using the box-type extractor for Oxalate / Carbonate precipitation). The rare earth mining, mineral processing and rare earth oxide plant was designed and engineered. Plant equipment was specified suppliers quotations obtained for the main items.

Rare Earth Minerals Processing There are two major REE ore minerals from which predominantly LREE can be extracted with relative ease: bastnaesite and monazite. Bastnaesite, a fluorocarbonate mineral and monazite, a phosphate, contain predominantly either cerium, lanthanum or yttrium.
The Gakara project is one of the highest grade rare earth element mining projects globally, with an estimated in situ grade of 47-67% Total Rare Earth Oxide (‘TREO’), and the company is targeting a production rate of 5 000 tpa by the end of 2018.
“Rare Earth Elements are vital to the development and manufacturing of high-tech devices such as computers, cell phones, and our national defense systems,” said U.S. Secretary of Energy Rick Perry. “The current difficulties and high expenses associated with REE extraction has left the U.S. dependent on foreign REE imports.
Rare earth elements (REE) have become a highly valuable commodity due to their increased use in emerging technological applications. The future exploitation of areas with high REE content will play a strategic geopolitical role around the world, as shown in a previous article.
