gold without cynide Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
