  • Gold processing Britannica

    They were the type most commonly mined in antiquity. Exogenetic gold can also exist as oxidized ore bodies that have formed under a process called secondary enrichment, in which other metallic elements and sulfides are gradually leached away, leaving behind gold and insoluble oxide minerals as surface deposits.

  • Oxidation and Secondary Enrichment of Gold Deposits

    The supergene enrichment of gold in deposits may take place by a simple mechanical process, by chemical means, or by a combination of these. First, the enrichment may be primarily the result of the chemical removal of a large part of the gangue minerals, in which case the gold migrates slowly downward by gravity or is left behind as a residual

  • Enrichment of Ore or Concentration of Ore

    The process of removal of gangue particles from an ore to increase the percentage of metal in ore is called enrichment of ore. The processes used for removing the impurities from ores depend on the difference between physical or chemical properties of the ore and of the impurities.

  • Copper Concentrate Enrichment Process

    Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite coated pyrite and are difficult

    First, the enrichment may be primarily the result of the chemical removal of a large part of the gangue minerals, in which case the gold migrates slowly downward by gravity or is left behind as a residual component. Such enrichments require no chemical movement of the gold; the lodes simply weather down and the gold collects mainly by gravity in the accumulated residuum.
