    摘要: A sulfur dioxide free process for the production of high purity metallic copper from copper-matte wherein copper-matte is leached under oxidizing conditions in a ferric-containing acid copper sulfate electrolyte leach assembly including one or more leach reactors to yield a copper-rich electrolyte, and copper cathode is produced in an electrowinning assembly which is physically decoupled from the leaching assembly and may include one or more electrowinning cells. The process operates at ambient pressure and temperatures less than the boiling point.

    摘要: The subject invention pertains to the use of non-toxic heavy liquids and slurries in the separation of components of ores, concentrates, residues, soils, and scrap. Specifically exemplified herein is the use of cesium and/or rubidium salts in separation processes. These salts are particularly advantageous because of their high specific gravity and solubility in water and, their low solution viscosities.
