  • Gold Recovery 101

    process discussed above. Instead of cyanide leaching of the cyclone overflow the gold and sulfide minerals are recovered by flotation. The particles in the cyclone overflow are mixed with chemical reagents to render the surfaces of the gold-containing sulfide minerals hydrophobic (metallic gold is naturally hydrophobic).

  • Gold Recovery And How To Choose The Right Process

    Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade

  • Gold Ore

    Gold ores are classified “free-milling” and “refractory” based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an appropriate
