Hexavalent chromium leaching influenced factors in the weathering chrome slag
The distribution of hexavalent chromium in the weathering slag was studied,as well as the influenced factors of aqueous agent leaching chromium.Results showed an optimal leaching condition:the chromium particle size is 100-200 mesh,the liquid-solid ratio is 20∶1,the leaching time is 4h 8h.Enhanced temperature and reduced pH value are benefit to hexavalent chromium leaching.Considering the equipment corrosion of low pH,the optimal pH value is 3-4.
