Waste streams subject to metal recovery. Waste streams subject to metal recovery processes can be roughly divided into leachate-concentrated streams (i.e. >1 g/L) coming from extraction processes applied to solid mining and metallurgical wastes (for review see Whitworth et al.

Generic flowsheets of each process were drawn up and used to establish the individual LCA spreadsheet models. Each flowsheet was constructed at a level of detail consistent with publicly available process data. This generally resulted in a flowsheet of three to five process steps, eg mining, mineral processing, smelting and refining.

A pyrometallurgical process is used for sulfide ores. The extraction of the ore is done by froth flotation and thickening according to the density of the particles. 3. Purification. For oxide ores, the pregnant leach solution is sent to a solvent extraction process to concentrate the copper in the solution in a process called "hydrometallurgy."
The less dense ore rises in the froth to be collected, while the heavier gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and - in the case of copper/ molybdenum ores - separates molybdenite from copper sulfide. The resulting MoS 2 concentrate contains between 85 and 92% MoS 2. Further treatment ...
