Metallic Mineral Mining: The Process the Price

18-11-2015  4 Metallic Mineral Mining: The Process the Price Metallic mineral mining refers to the extraction of both ferrous and nonferrous metals. Sulfide mining is a term often used to describe the mining of nonferrous metals, including copper, lead, zinc, and others, because these metals frequently are bonded to sulfur, forming sulfide compounds.

Product and chemical recovery in mining and minerals

in mining and minerals In the leaching/digestion process, the mineral is extracted from the ore by reacting with an acid or base. The preg-nant liquor that contains the mineral is then sent to a precipitation circuit to pre-cipitate the mineral, after which it under-goes thickening and filtration processes to produce high-grade concentrate.
