PLASMA SMELTING OF UNCONVENTIONAL ORES AND …

ores can be subjected to further processing to improve the cyanidation-based recovery rate, but often at greater expense. Refractory behaviour in gold ores includes those ores in which the gold is less accessible physically, typically because the gold particles are extremely fine and locked inside a protective layer of material. This You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag …
