The concept of microorganisms as chemical reagents (flocculants, flotation modifiers and flotation collectors) is quite new. Potential uses for microorganisms include their use in place of certain conventional flotation reagents and as flocculating agents in minerals engineering processes. In addition, in some studies microorganisms have been used to modify mineral surfaces and, thus, the flotation or flocculation of the minerals. Preconditioning with various microorganisms such as Thiobacillus ferrooxidans are known to cause depression of pyrite selectively in coal flotation.
