摘要：

The kinetics of pyrite dissolution by hydrogen peroxide in perchloric acid were investigated, The effects of stirring speed, temperature, hydrogen peroxide acid perchloric acid concentrations and particle size were examined. The activation energy was calculated to be 57 kT/mol, indicating that the dissolution of pyrite is chemically controlled. The order of the reaction with respect to hydrogen peroxide was found to be approximately 1. The perchloric acid concentration had practically no effect on the rate of pyrite dissolution. In addition, the effects of H+, ClO4-, and SO42- ions were examined.
