magnetic separation of iron pellets

Wet High Intensity Magnetic Separation

Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, highquality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the
