Ways to Recover Gold from Cyanide Heap Leach Solutions

Activated carbon prepared from coconut shells is preferred for gold recovery from alkaline cyanide solutions. These carbons are distinguished by high surface areas (> 1000 m²/g) and a narrow range of pore sizes (10-20 A) and good mechanical strength. Carbon regeneration is required to remove organics and restore the intrinsic chemical activity of the carbon. After removal of carbonate

The Metallurgy of Cyanide Gold Leaching An Introduction

20/10/2014 In a typical application, a slurry of the ground ore is mixed with cyanide in the presence of activated carbon. The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at

Cyanide Use in Gold Mining Earthworks

Cyanide Use in Gold Mining. What is cyanide? Cyanide is a rapidly acting, potentially deadly chemical. “Cyanide” can mean any one of various compounds containing the chemical group CN: one atom of carbon (C) and one atom of nitrogen (N). Because it is organic, it reacts readily with living organisms. Cyanide easily combines with many metals making it useful in separating metals like
