The experiment uses a process of acid leaching+oxidation impurity removal to treat newly mined manganese ore from a domestic manganese ore.The experimental results show that when the sulfuric acid concentration is 540 kg/t,the leaching temperature is 90℃,and the leaching time is 6 h,the leaching rate of manganese is 75.05%,and the leaching rate of iron is 55.41%.After oxidation impurity removal,the iron and phosphorus content in the solution decreases by 99.99%,less than 1 mg/L,and the Mn content is 30.38～35.86 g/L,meeting the requirements for preparing qualified electrolytes.
