Outline
An experimental research was carried out on leaching of marine sedimentary manganese deposit from Xinjiang, and effects of acid-to-ore ratio, leaching temperature, leaching time, and ore particle size on manganese leaching rate were investigated. The results indicate that effective separation between elements of silicon and manganese in the solution can be actualized by increasing leaching temperature and prolonging leaching time, which can also benefit the formation of large-particle precipitates and enhancement of filtering speed. After manganese ores with particle size of -150 μm are leached at room temperature for 4 hours, with acid-to-ore ratio of 0.56, the manganese leaching rate can be up to 86.32% and a leaching residue rate is 61.12%, while the mass concentration of manganese ions in the manganese sulfate leachate is 41.29 g/L.
