Innovations in Copper: Mining & Extraction: Producing

By the use of the SX/EW process, copper can now be extracted away from the iron and other impurities in solution and further purified and reduced to metallic metal by electrolysis without ever having to be melted. Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore.

Biomining: metal recovery from ores with microorganisms

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water
