Our Manganese ore manganese has high grain dense, high mechanical strength, chemical activity, not broken.
The insoluble natural manganese ore had passed washing grinding, crushing, drying, magnetic separation, screening, dust and other processing techniques, then be formed into small particle. Then processed manganese sand with a certain level by blending. It has the best water filter gradation ratio, making it the largest surface area per unit volume, interception in the strongest ability, oxidation catalyst and the smallest back washing loss rate. Manganese sand filter the appearance of dark brown, nearly circular, the main ingredient is manganese dioxide content between 35% -54%.
