Factors influencing the moist oxidation of iron pyrites
Experiments were conducted to study the rate of oxidation of pyrite under conditions of varying pH, temperature and oxygen concentration. The rate of oxidation appears to be slightly increased below pH 3.00. In the basic range the oxidation is retarded as pH 9.00 is approached. Increases in temperatures cause increases in the rate of oxidation of pyrites. Corresponding decreases in the pH values are also noted. The rate of oxidation is increased by increaseing the concentration of oxygen. From these results, the possible use of pyrite in alkaline soils in the prevention of chlorosis caused by iron deficiency seems feasible.
