iron sulphide in copper floatation concentrate

  • Copper Ores Sulfide Minerals

    When liberated, typical copper sulphide minerals are relatively easy to float. When there are no overriding metallurgical issues, producing a sufficiently high copper concentrate grade is often the focus. Often the primary grade control issue relates to iron sulphide minerals since these also float with the copper, diluting copper concentrate grades.

    The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities.
