Gold and Cyanide. The discovery that gold was soluble in weak solutions of potassium cyanide mid 19th century presented a major tool to gold miners, who could now dissolve the gold in the ore and discard the waste rock. Modern cyanide plants typically use a cyanide solution of 0.05 NaCN to dissolve gold from the ore.
