Manganese ore is a mineral with a very high utilization value, generally grayish-white with a metallic luster. Manganese ore has a wide range of industrial uses, mainly for iron smelting and alloy manufacturing, as well as in the chemical, light, building materials, and other industries. In the steel industry, the use of manganese ore is as high as 90~95%, and most of them are poor ores, so ore dressing is needed for effective separation and enrichment. There are 150 known manganese minerals, among which manganese oxide ore and manganese carbonate ore are the most economically valuable. However, manganese ore processing requires a complete understanding of the ore’s composition, properties, and characteristics to select the best beneficiation equipment to achieve the best ore-dressing effect. Usually, the processing of manganese oxide ore mainly adopts gravity separation, and the processing of manganese carbonate ore mainly adopts magnetic separation. According to the nature of the ore, crushing, screening, grinding, washing, and other processes are also indispensable in the entire processing line.
