南斯拉夫报道了研究用硫酸中的重铬酸钾氧化黄铁矿的动力学所得结果。探索了温度、重铬酸盐和硫酸的浓度、粒度和搅拌速度的影响。结果表明，反应是化学控制的，活化能为50KJ／mol。重铬酸根离子浓度对黄铁矿氧化速率无影响（零级），而硫酸浓度为一级关系。同时发现黄铁矿的氧 Yugoslavia reported the kinetics of the oxidation of pyrite with potassium dichromate in sulfuric acid. The effects of temperature, dichromate and sulfuric acid concentration, particle size and stirring speed were explored. The results show that the reaction is chemically controlled and the activation energy is 50 KJ / mol. Dichromate ion concentration had no effect on pyrite oxidation rate (zero order), while sulfuric acid concentration was of a first order. Also found pyrite oxygen
