Manganese Ore Enrichment

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%.
