While the romantic picture of gold mining focuses on nuggets, the reality is that gold is typically recovered from ores containing >10 ppm of the metal. Thus, the main challenge is concentrating this trace amount. The principal technology involves the leaching of gold from the ore by treatment with a solution of cyanide. Thus, the typical first step is comminution to expose the gold to the extracting solution.
