Copper Mining and Processing: Processing of Copper Ores .

Since each mine site is unique in its mineral composition, concentration, and quantities, the most economical and profitable processing of ore must be determined by the mine planners. When it is economically feasible, a mine may extract both types of copper minerals; when it is not possible, mines will only process either.

copper processing | Definition, History, & Facts | Britannica

The sulfide material, known as matte, contains from 45 to 70 percent copper, depending on the particular process. Gangue minerals and oxidized impurities, including most of the iron, react with the flux and form a light, fluid layer of slag over the matte. A certain percentage of the volatile impurities, such as sulfur, is oxidized.

Copper removal from acid mine drainage-polluted water using .

Copper (Cu) is one of those hazardous metals and a key pollutant that often exist in AMD. The acidity and high concentration of dissolved copper makes such AMD toxic to most organisms [14, 15]. To date, a wide range of AMD treatment systems have been developed based on chemical, physical and biological processes,.

Nickel - Wikipedia

In hydrometallurgical processes, nickel sulfide ores are concentrated with flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. The nickel matte is further processed with the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of cobalt and nickel. Then.
