Heavy Metal Mining Using Microbes Annual Review

2019-7-17  1 1Definitions: The term bioleaching refers to the conversion of an insoluble metal (usually a metal sulfide, e.g., CuS, NiS, ZnS) into a soluble form (usually the metal sulfate, e.g., CuSO4, NiSO4, ZnSO4). When this happens, the metal is extracted into water; this process is called bioleaching (48, 89).

2019-2-4  1.1.3.2 Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called ‘hydraulic mining’) are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer

Copper Mining and Processing: Everything you Need

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.
