A similar process uses potassium cyanide (KCN, a close relative of sodium cyanide) to produce potassium gold cyanide (KAu(CN) 2). Few other methods exist for this extraction process. Chemical feedstock. Several commercially significant chemical compounds are derived from cyanide, including cyanuric chloride, cyanogen chloride, and many nitriles.
Apr 21, 2016 The cyanide process has the advantage of producing precious metals in bullion form with the highest net return from those gold and silver ores amenable to cyanidation. The counter current decantation washing circuit has been found to be a most economical method for

Oct 01, 2009 For batch grinding, the artisanal ball mills are ideal for cyanide leaching. The mill-leaching process was successfully implemented in Portovelo, Ecuador. About 95% of the gold was leached from a pre-concentrate (with 17.3 g Au/tonne) obtained by grinding
fine gold particles after grinding the ore in a ball mill and concentrating by panning. Miners separate the gold from the amalgam by “burning” the amalgam, volatilizing the elemental gold mining operation in Portovelo, Ecuador (Veiga et al., 2009). However,

Ore reclaim tunnel and conveyor leading in to the grinding building. Gold concentrate thickener nearing completion. Carbon-in-leach tanks are almost finished.
Replacing mercury addition with cyanidation in ball mills was implemented in one artisanal gold mining operation in Portovelo, Ecuador, achieving 95% of gold extraction in 8 h of mill leaching. This technique demonstrated a drastic improvement in gold recovery. It was found to be a simple, inexpensive technique well accepted by local miners.
