Effects of Acidithiobacillus ferrooxidans and Fe(III) on pyrite-pyrolusite bioleaching process

open access: yes, 2017
The beneficial effects of Acidithiobacillus ferrooxidans and/or Fe(III) on manganese bioleaching from a low-grade manganese ore were confirmed. The results showed that the rate of manganese bioleaching increases with the amount of A.

Effect of Acidithiobacillus ferrooxidans on pyrolusite bioleaching

open access: yes工程科学学报, 2019
Biohydrometallurgy is an increasingly popular ore extraction technology and is especially applicable for low-grade ores. In particular, Acidithiobacillus ferrooxidans (A. ferrooxidans) is by far the most widely used bioleaching microorganism for leaching ores, including for sulfide ores and manganese dioxide ores.
