The ore enrichment process is designed to increase its manganese content to just over 50% through magnetic separation. Part of the enriched ore is directly sold, while another part goes through a pelletizing process in which the mineral is mixed with coke and exposed to high temperatures, which increases its manganese content to around 56%.


What is Manganese Ore? Manganese is a silver metallic element with an atomic number of 25 and a chemical symbol of Mn. It is not found as an element in nature. It occurs in many minerals such as manganite, sugilite, purpurite, rhodonite, rhodochrosite, and pyrolusite. It is also found in many mineraloids such as psilomelane and wad.


For example, the Lehua manganese ore deposit in Jingdezhen, one of the largest asbolane mines in Asia and an important source of blue pigment recorded in ancient literature, is located in a subtropical monsoon region with high average annual temperature and seasonal temperature differences, abundant rainfall, and thick vegetation.

The manganese ore resources in China are mainly distributed across Guangxi, Hunan and Guizhou provinces. The Wafangzi mine, situated in the north of China (Inner Mongolia), is one of the country's largest manganese reserves, with an estimated 37.7 million tonnes of manganese ore grading 24% manganese metal.

Manganese ore containing 20% or more manganese has not been produced domestically since 1970. Manganese ore was consumed mainly by six firms with plants principally in the East and Midwest. Most ore consumption was related to steel production, either directly in pig iron manufacture or indirectly through upgrading the ore to ferroalloys.
