This project will: develop improved approaches to sustainably extract PGMs (platinum (Pt) and palladium (Pd)), selenium (Se), tellurium (Te), and precious metals (gold (Au) and silver (Ag)) from Se crude residue ( Se sludge) produced from anode slime processing at Kennecott Utah Copperton Concentrator (KUCC), develop Techno-Economic Analysis (TEA) model to assess economic impacts of the proposed processes, and develop comparative Life Cycle Assessment (LCA) model to evaluate the environmental impacts of the proposed processes as compared to currently used practices.
