Mechanism of fluoride inhibition on bioleaching bacteria and competitive complexation of ferric ions
工程科学学报, 2018 A bottleneck occurs in the application of bioleaching technology to fluoride-containing ore. The reason for this is that fluorine has a strong inhibitory effect on leaching bacteria with the dissolution of fluorine-containing gangue minerals.
