AbstractIn H2SO4-HNO3-H2O-O-2 system, the effects of solution composition, opreration factors and several additives on the reaction rate of pure pyrite have been studied in detail under the pressure condition. The results indicated that after leaching, the product percentage of oxidation residue is about 5 wt.-% and its composition mainly is alpha-S-0 and H3OFe3(SO4)(2)(OH)(6). In the presence of HNO3, the reaction rate increased by about 10 times.; In H2SO4-HNO3-H2O-O-2 system, the effects of solution composition, opreration factors and several additives on the reaction rate of pure pyrite have been studied in detail under the pressure condition.
