Manganese Ore (25-35% Mn)

Manganese Ore (25-35% Mn) from Pakistan

Low-to-medium grade manganese ore in the 25-35% Mn range is an important industrial raw material, especially for ferro-alloy smelters that blend it with higher-grade ores to optimize furnace feed chemistry and reduce costs. The ore has a dark grey to black metallic appearance with a dense, hard structure. Pakistan’s manganese-bearing formations in Balochistan and Lasbela produce ore in this grade range in consistent commercial volumes.

Available Forms

• Run-of-mine (ROM) lumps: 10-250 mm

• Crushed lumps: 10-75 mm, 5-25 mm

• Screened fines: 0-10 mm, 0-5 mm

• Custom sizing available

Industrial Uses

• Ferro-alloy blending: 25-35% Mn ore is blended with higher-grade manganese ore (40%+ Mn) in submerged arc furnaces to produce ferromanganese and silicomanganese at optimized cost. Smelters commonly use 20-40% low-grade ore in their feed blend

• Silicomanganese production: Lower-grade manganese ore combined with quartz and coke for SiMn production, where the higher SiO₂ content in low-grade ore can be beneficial to the slag chemistry

• Manganese chemical production: Feedstock for manufacturing manganese sulphate (MnSO₄), manganese dioxide, potassium permanganate, and other manganese compounds through hydrometallurgical and pyrometallurgical routes

• Cement manufacturing: Manganese ore fines are added to cement raw mix to provide MnO, which influences clinker mineralogy and cement color. Typical addition rates are 1-3%

• Brick and tile coloring: Ground manganese ore is used as a natural colorant in clay bricks, roof tiles, and ceramic products, producing brown and black tones

• Water treatment media: Manganese-coated filter media for removing dissolved iron and manganese from groundwater supplies

• Road construction: Manganese ore aggregates are used in asphalt and road base applications where high density and abrasion resistance are beneficial
