2019-7-17  Abstract The use of acidiphilic, chemolithotrophic iron- and sulfur-oxidizing microbes in processes to recover metals from certain types of copper, uranium, and gold-bearing minerals or mineral concentrates is now well established.During these processes insoluble metal sulfides are oxidized to soluble metal sulfates. Mineral decomposition is believed to be mostly due to chemical attack by

Mining the mineral microbiome ScienceDirect

2018-12-3  Summary. Microbes interacted with minerals for billions of years before multicellular organisms started to evolve. A better understanding of the mineral microbiome and its mechanisms of mineralisation and solubilisation could help with the exploration, production and ultimate recycling of mineral resources. Michael Gross reports. Previous article.
