What is The Extraction of Manganese? - Xinhai
This extraction of manganese ore includes heavy medium dressing method, jig separation, concentrating table separation, etc. This kind of ore has a low manganese content, which is usually under 30%. For this kind of ore, the manganese grain size is small and the mud content is large, so the extraction of manganese is complex.
