Hydrometallurgical Treatment process for the extraction of Precious Metals, base and rare

摘要

This Invention relates to a hydrometallurgical process for the Recovery and separation of Precious Metals, Rare or valuable basis, such as the Platinum Group Metals (pgms)Gold or Silver, and other valuable and rare metals such as Nickel, Cobalt, Copper, Rare Earth Elements (REE), Yttrium and Scandium and Thorium, Uranium, zinc, Manganese, cadmium,MOLYBDENUM, Titanium, Tin, and other minor Elements such as Vanadium, Gallium and Germanium from a feedstock comprising ores and other materials.Particularly, the process involves quantitative Elimination of Base ElementsAdditional Rare Bargain and to increase the efficiency of additional Treatment of solids to the Recovery and / or recycling of valuable Metals and / or the separation of precious metals fromThe Pressure leaching residues, and can be integrated into one or more existing processes of extraction of valuable Elements.
