Abstract
The paper shows: (a) the results of pyrite oxidation by gaseous oxygen in water suspension at high temperatures in an autoclave and (b) the results of simultaneous leaching of Mn4+ from pyrolusite ore by H2SO4 and FeSO4, the products of pyrite oxidation. It was shown that both processes occurred successfully with almost complete pyrite oxidation and a high degree of leaching of manganese. Both processes occur according to the laws of first-order reactions compared to the quantities of FeS 2 and MnO2 in suspension, with activation energies of 65±0.8 kJ/mol and 97±0.5 kJ/mol, respectively.
