The kinetics of acid formation are dependent on the availability of oxygen, the surface area of pyrite exposed, the activity of iron-oxidizing bacteria, and the chemical characteristics of the influent water. The principal iron-oxidizing bacterium involved in accelerating pyrite oxidation is Thiobacillus ferrooxidans. The Bureau of Mines has previously reported the results of full-scale field tests that showed how anionic surfactants (cleansing detergents) can be used to reduce the activity of T. ferrooxidans and thereby abate acid formation. After a brief discussion of the literature, this paper will review the surfactant solution technique and report progress on two alternative procedures.
