Microbial mining of ore zflotation

MICROBIAL MINING. MICROBIAL MINING. The central role of bacteria in the leaching of copper from low-grade ore long went unrecognised. The minerals industry now stands to gain from the application of novel methods of microbiological technology . by Corale L. Brierley (Published in: Scientific American, 247, 42 50, 1982, here without accompanying figures)

    Review of Potential Microbial Effects on Flotation

    Microorganisms enter the flotation process mainly from intake water and ore material. The diversity and number of microorganisms can vary significantly from mine to mine. In flotation, the conditions including oxygen levels, temperature, and nutrients from ore, intake water, and reagents are often favorable for the microbial growth. The mining industry aims to close the water loops, which is

    Aug 15, 2021 A pyritic sample obtained from the tailings of a sulfide copper-zinc ore flotation plant (Au:1.15 g/t) and a carbonaceous-argillaceous slate (CAS) sample (Au:2.17 g/t), were examined to extract the gold using microbial leaching (Daibova et al., 2019). The researchers bioleached the gold by the separate “stimulation of the natural microbiome
