Abstract
The technical principle and process of leaching reaction for high silicon low grade manganese ore and pyrite under the pressurized condition is researched,and the effect of the following process on manganese leaching efficiency conditions are discussed,which are sulfuric acid dosage,pyrite dosage,leaching temperature,leaching time,liquid-solid ratio and so on. The experimental study result shows that the leaching efficiency of manganese can reach to more than 97% under the best leaching conditions.
