Bioleaching presents several technological, environmental and economic advantages as compared with pyrometallurgy, as well as some limitations. Results: In this work a general panorama of copper mining and biomining, the influence of the most relevant operating variables and their present and future situation in Chile are presented and discussed.
bioleaching plant in copper industry even though it has big copper mine with low grade of ore. Through this comparison, the factors affecting the bioleaching implementation were clarified and the future applicability of bioleaching into copper industry was estimated. 2. Chile: a mining developed country . 2.1 Copper industry in Chile
Early application of bioleaching to copper mining centred in its recovery from dumps . This is a low technology process and renders low productivities and recoveries. Nevertheless, dump bioleaching is economical, mainly because it recovers copperCited by: 28
