Cyanide Leaching Of Gold Mine

Cyanide Leaching Of Gold . 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. Chemically, it is a rather simple reaction: 4 Au + 8NaCN +O2 + 2 H2O = 4 NaAuCN

Cyanide Use in Gold Mining Earthworks

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used
