While jewellery is the end of the road for most mined gold, there are many ways it occurs in nature.

view moreGold/silver ores rely on a good solubility for both metals, which is favored by high cyanide levels, particularly for silver. Often cyanide levels are restricted to keep down consumption and detox costs, but this can also reduce metal recovery levels. By eliminating detox costs, cyanide levels can be increased to better suit metal recovery ...
