  • Copper Essential Chemical Industry

    Data from 1 International Copper Study Group, 2015. 2 U.S. Geological Survey, Mineral Commodity Summaries, 2016. Manufacture of copper. About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (CuFeS 2) (the most abundant copper ore), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). These ores contain typically only about

  • Rare earth element Processing ores Britannica

    Rare earth element Processing ores All rare earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.

  • Considering the effect of pulp chemistry during flotation

    Within the flotation process the pulp phase chemistry has a strong effect on the froth phase and therefore the manipulation of pulp chemistry factors such as the pulp potential (Eh), pH, dissolved oxygen (DO) and ionic strength (IS) can improve flotation performance.

  • Molybdenum

    Molybdenum is a chemical element with symbol Mo and atomic number 42. The name is from Neo Latin molybdaenum, from Ancient Greek molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in
