Present and future commercial applications of biohydrometallurgy
Hydrometallurgy, 1999Modem commercial application of biohydrometallurgy for processing ores became reality in the 1950s with the advent of copper bioleaching by what was Kennecott Copper Corporation. Early application entailed dump leaching of low-grade, low-value, run-of-mine material.

Industrial Practice of Biohydrometallurgy in Zambia
2015Bio-hydrometallurgy technology was applied for the extraction of copper from the raw ores of Chambishi Mine in Zambia. A copper extraction of 93.29% was obtained for small scale column bioleaching within 63 days, while a copper extraction of 89.05% was achieved for large scale column bioleaching in 90 days, thus confirming the amenability of the raw ...

Airlift Reactors: Characterization And Applications In Biohydrometallurgy
2007Over the last decade biooxidation for the pretreatment of refractory sulfidic gold concentrates and the bioleaching of copper have been applied with increasing frequency. In addition to heap-leach facilities for the bioleaching of copper, several biotank oxidation plants are also operational for the pretreatment stage in the processing of refractory ...

Biohydrometallurgy: What is its Future?
Advanced Materials Research, 2009Bioleaching/minerals biooxidation and bioremediation have been widely used commercially for heap/dump bioleaching of secondary copper sulfide ores, sulfidic-refractory gold concentrates and treatment of acid rock drainage. Technical and commercial challenges, identified in this paper, remain for bioleaching of primary sulfides and complex ores.

Biohydrometallurgy and the environment: Intimate and important interplay
Hydrometallurgy, 2006All life forms have absolute requirements for a wide range of metals. For some prokaryotic microorganisms, metals have not only a nutritional requirement but also pivotal roles in energy generation, by acting as electron donors or electron acceptors. In the last half of the twentieth century, scientific technologies emerged that harnessed the abilities
