    How and why do we produce gold and copper concentrates

    There are generally two different types of downstream treatment options to extract the gold, copper and silver from the concentrate smelting and oxidation. There are three types of oxidation process roasting, pressure oxidation and bio oxidation.

    Gold extraction

    Gold extraction refers to the processes required to extract gold from its ores. (e.g. copper) concentrate, These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both.

    ON SITE PROCESSING VS. SALE OF COPPER

    Over the years, treatment charges have varied quite widely, since this is essentially a free market, i.e.supply of concentrate vs smelting capacity. When copper prices are low, naturally supply of concentrate dries up fairly quickly, whereas smelters keep going, thus there is a rough relationship as one might expect between copper prices and treatment charges.
