Introduction of MercuryFree Gold Extraction to Small

Methods for gold extraction without the use of mercury are available One method has proven to be implementable and safe4 This method is called the ‘mercuryfree gold extraction method’ and involves smelting with borax Smallscale gold miners in Benguet in the northern Philippines invented the mercuryfree gold extraction methodIn this work, two hydrometallurgical processes for gold recovery are explored for a smallscale gold mining case study located at Ponce Enriquez, Azuay, Ecuador The hydrometallurgical systems consider the use of sodium cyanide and sodium thiosulfate as leaching agents, with and without the incorporation of a subsystem for residual mercury removalMinerals Special Issue : Hydrometallurgy in Gold Less mercury, more gold and better health (Gold in a shop in Kalimantan, Indonesia) Manual for Training Artisanal and SmallScale Gold Miners/Veiga, MM et al/Vienna, Austria: GEF/UNDP/UNIDO, 2006, 144p 1 mercury pollution, 2 artisanal gold mining, 3 gold processingManual for Training Artisanal and SmallScale Gold MinersiGoli is a simple, safe, and highly effective method of gold extraction that produces an extremely pure product It consists of leaching the gold concentrate with dilute hydrochloric acid and bleach After the solids are filtered, the gold is precipitated out with sodium metabisulphateIGoli MINTEK MINTEK SmallScale Mining in Africa: Tackling Pressing Environmental Problems With Improved Strategy Gavin Hilson Smallscale mining lowtech mineral extraction and processing has long been an important industry in Africa For centuries, operations have provided inhabitants of the rural, more impoverished regions of the continent with aSmallScale Mining in Africa: Tackling Pressing
