Practica in Process Engineering II Extraction
Practica in Process Engineering II Extraction Introduction Extraction is a process in which one or more components are separated selectively from a liquid or solid mixture, the feed (Phase 1), by means of a liquid immiscible solvent (Phase 2). The transfer of the components from the feed to the solvent is controlled by the solubility behavior
The cuprex metal extraction process: Recovering copper ...
The Cuprex™ metal extraction process produces cathodegrade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrates. The process incorporates several novel steps to overcome the major problems associated with earlier chloridebased processes, including mild leaching conditions using ferric chloride as leachant and solvent extraction of copper usinga ...
