Moreover, all eleven metals are, to varying degrees, produced as byproducts during the production of other commodities: Ag is primarily produced as a byproduct from lead-zinc, copper, and gold mines; Cd, Ge, and In are produced mainly as byproducts of zinc or polymetallic base metal mining; Ga is produced mainly as a …
America's largest critical minerals mine
This move elevates Red Dog from an important base metal mine that produces 4% of the world's zinc – along with lead, silver, and germanium byproducts – to a globally significant critical minerals operation that outproduces mines that supply the rare technology metals that typically come to mind when one thinks about critical minerals.
The Challenges of Reusing Mining and Mineral-Processing …
Mining and mineral-processing wastes—the solid and liquid materials generated after mining and ore processing at or near mine sites ()—have no current economic use.A number of environmental problems are associated with the disposal of this waste, including contamination of streams and lakes and pronounced landscape …
How can metal mining impact the environment?
Operations and waste products associated with metal extraction and processing are the principal causes of environmental concerns about metal mining. Concerns include: Physical Disturbances. The largest physical disturbances at a mine site are the actual mine workings, such as open pits and the associated waste rock disposal areas.
The mining value chain: A hidden gem | McKinsey
The mining value chain— which includes everything from extracting raw material to delivering products to customers—is the backbone of the industry.
