this process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. the best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries..closure of artisanal small scale gold mining processing plants in …,journal of management and sustainability; vol. 5, no. 2; 2015 issn 1925-4725 e-issn 1925-4733 published by canadian center of science and education 41 closure of artisanal small scale gold mining processing plants in ecuador brandon nichols1, marcello veiga 1, dirk van zyl & andre moura xavier1.(doc) vat leaching and elution plant - gold processing …,this has attracted major companies such as ashanti goldfields, anglogold; barrick gold corp; placer dome inc., as well as a host of small scale miners. currently no large scale mine is using this method of leaching but small scale miners due to capital limitation, they have employed vat-leaching (vl) process which is cheaper than tank leaching (tl) used in modern industries..strategies for sustainable gold processing in the artisanal and small-scale …,plant for processing or extraction of gold or gold bullion that is not operated exclusively for the benefit of an operator who mines the gold. in this set up, artisanal and small scale miners
