Because of inherent inefficiencies in mining extraction processes, not all of the desired mined
materials are able to be captured. This results in resource waste, which is often deposited into
wet fields, waste piles and storage ponds. These occupy useful land, are commonly a source of
environmental pollution, and can potentially contaminate vast acreage upon a catastrophic
dam collapse or containment breach.
The Company’s patented Chelok® polymers have been shown to capture rare earth and other metals from waste products produced from phosphogypsum (fertilizer production), bauxite residue (aluminum mining), coal ash (electric utilities), and Marcellus Shale drill cuttings (natural gas industry). Analysis has shown that these polymers afford a nearly complete removal of useful components and impurities in these waste products. Resource waste is significantly reduced, and the need for waste containment sites is diminished.
