Biohydrometallurgy process
WebBiomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching. WebOct 18, 2003 · An early documented commercial application of a biohydrometallurgy process in the mining industry was for copper extraction from mine waste (Zimmerley et al. 1958). The acidophilic iron oxidizing Thiobacillus ferrooxidans was recognized as a means to maintain iron in the oxidized ferric form to serve as the oxidant for sulfide copper …
