Manganese ore and its compounds are used in various fields of national economy, among which the iron and steel industry is the most important field, and the amount of manganese accounts for 90% ~ 95%, which is mainly used as deoxidizer and desulfurizer in ironmaking and steelmaking, as well as making alloys.

The rest 10% ~ 5% manganese is used in other industrial fields, such as chemical industry (making various manganese-containing salts) and light industry (used in batteries, matches, printing paint, soap making, etc. ), building materials industry (colorants and decolorants for glass and ceramics), national defense industry, electronics industry, environmental protection, agriculture and animal husbandry, etc.

Manganese has a very important strategic position in the national economy.

Extended data:

The vast majority of manganese ores in China belong to poor ore, so mineral processing must be carried out. However, most manganese ores are fine or micro-fine, and there are a considerable number of high-phosphorus ores, high-iron ores and symbiotic beneficial metals, which brings great difficulties to mineral processing.

The commonly used mineral processing methods of manganese ore in China include mechanical mineral processing (including ore washing, screening, gravity separation, high intensity magnetic separation and flotation), pyrometallurgical enrichment and chemical mineral processing.

Ore washing is often accompanied by screening, such as washing with water directly on the vibrating screen or sending the ore (clean ore) obtained by the ore washer to the vibrating screen for screening. Screening can be used as an independent operation to separate products with different granularity and grades for different purposes.
