The sulphatization of low grade manganese ore with iron pyrites has been studied. The effect of reaction period, temperature, ratio of manganese to sulphur, particle size, surface area and packing density was investigated and the extent of sulphatization was reported as recovery of manganese sulphate. Under optimum heating time of 2 h at 600°C with finely powdered (−150±200 mesh BSS pyrite and −300±325 mesh manganese ore) reactants, the conversion to manganese sulphate was 82%.
