Overall, the cyanide process is very efficient. A gold ore containing less than one gram of gold per ton can, in some cases (and depending on the gold price), be profitably treated. A modern cyanide mill recovers or extracts 95% to 98% of the gold in the ore. In a cyanide mill, lime and cyanide are added to the ore pulp in the grinding circuit.
