    Ground ore or treated concentrate is placed in a weak solution of sodium cyanide which dissolves gold and forms a slurry of gold-bearing solution and other solids. Some ores may be treated by heap-leaching. This involves sprinkling a weak cyanide solution over an open pile of ore stacked on an impervious base.
