Extraction of Gold

The residue is extracted with 0.35 per cent, solution of potassium cyanide, then with 0.08 per cent, solution, and ultimately with water. The extract is transferred to tanks, and the gold precipitated as a powder by addition of zinc. It is then washed out from the bottom of the tanks, dried, and freed from zinc by roasting and fusing.
