When magnetite occurs in lower-grade deposits, the ore is ground, and the concentrate is separated magnetically from the gangue with the ore in a water suspension. Low-grade ores that cannot be separated magnetically may need to be concentrated through washing, jigging, heavy media separation, or flotation. Magnetic separation is used to separate iron ores from less magnetic material and can ...

Agglomeration and Characterization of Nickel

The standardization applied to iron ore was followed. The best result of crushing strength was 98.52 daN/pellet. The agglomerates with approved crushing strength for use in electric furnaces were smelted to produce alloys containing nickel; the agglomerates were characterized by scanning electron microscopy. The alloy obtained was metallic ferronickel with sulphide precipitates. Therefore, MHP
