Processing of Magnetite Iron Ores

Although the majority of current steel production is supported by iron ore sourced from high-grade haemetite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed. Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation. The separation step between grinding stages progressively reduces the amount of material to be ground.

jigging of low grade iron ore

Lot of developments in iron ore processing have been taken place in recent years in many iron ore producing countries of the world. The emphasis was on development of a cost effective flow sheet to beneficiate the low-grade iron ores to produce concentrates suitable for blast furnace, sinter or pellet making. Some of the development features in the processing side are jigging, innovations in spiral concentrator, autogenous grinding, column flotation, high gradient magnetic separators (HGMS), fine screening etc. Jigging is a gravity-separation technique, where bulk materials are separated into light fraction, medium-density fraction and heavy-density fraction. It is one of the oldest methods of gravity concentration technique. Even today it is the widespread technology in coal preparation because of its high separation precision, cost-effectiveness and high throughput rate.

iron ore grinding technology

Application of more efficient grinding technologies developed in the last 20 years, including high pressure grinding rolls (HPGR) for fine crushing and stirred milling for fine grinding, has provided opportunities to further reduce the operating costs associated with comminution. Both technologies are already implemented in some magnetite processing operations, although in limited capacity.
