How To Leach Gold By Cyanide

Apr 07 2020nbsp018332Gold cyanidation also called cyanide leaching is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock which itself is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.

    Cyanide Leaching Mining Sgs

    Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process a cyanide solution or lixiviant is percolated through ore contained in vats columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
