Our manganese sand is manufactured from natural manganese ore with superior quality, high density, and excellent mechanical strength. It features strong chemical activity, resistance to fragmentation, and is insoluble in water. The processing involves meticulous water washing, grinding, impurity removal, drying, magnetic separation, screening, and dust removal.
Application Note: Manganese sand filter material is ideal for iron and manganese removal in drinking water filtration devices. (Note: MnO₂ ≥ 35% removes both iron and manganese; MnO₂ ≤ 30% is primarily for groundwater iron removal).
