| Abstract: | Pilot test on leaching low-grade rhodochrosite using industrial waste hydrochloride to prepare tetrahydrate manganese chloride was introduced.The results show that at the optimum process conditions of leaching temperature of 80 ℃,leaching time of 60 min,pH of 3.0,ratio of liquid to solid of 4∶1,leaching rate of manganese reaches 91.1%.Most of Ca can be removed simultaneous during leaching by addition MnSO4.Ca removing rate reaches 95% after preliminary concentrating.Mg removing rate reaches 86% when the excessive ratio of MnF2 is 1.0.The product of tetrahydrate manganese chloride can be obtained from purification solution after desulfidation and evaporation crystallization,which quality satisfying criteria of HG/T3816—2006,and recovery of Mn is over 72%. |
