  • Pyrrhotite - an overview | ScienceDirect Topics

    Mined sulfide ores contain pentlandite, pyrrhotite, chalcopyrite and gangue rock. A high-grade nickel concentrate is produced from these ores by the following minerals-processing techniques: a crushing and grinding the ores to liberate the nickel- and cobalt-bearing minerals from

  • Copper Ore Types: Sulfides vs. Oxides | An Investors

    sulfide ores are typically the most profitable ore type to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted

  • Effect of Gangue Mineralogy on Flow Sheet Design and Plant

    Copper- Fe-sulfide ore deposits typically have Cu grades varying from 0.5 to 5%. This equates to approximately 1.5 to 15% sulfide minerals, hence of the remaining ore mass is comprised of gangue minerals

  • US5074910A - Process for recovering precious metals from

    The present invention is a process to recover precious metals from . It involves chlorinating a mixture of an concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300° and 600° C. while stirring. The process converts precious metals in the elemental and forms into
