Flotation For Iron Ore Beneficiation

the grade upgrade of iron ore

Lower grade Iron ore cannot be used directly in metallurgical plants and needs to be upgraded to increase the iron content and reduce the impurity content. A process adopted to upgrade ore is called Beneficiation. Iron ore is being beneficiated all round the world to meet the quality requirement of Iron and Steel industries. Several techniques such as washing, jigging, magnetic separation, advanced gravity separation and flotation are being employed to enhance the quality of the Iron ore.

Due to the high density of hematite relative to silicates, beneficiation usually involves a combination of crushing and milling, magnetic separation if magnetite is present as well as heavy liquid separation. This is achieved by passing the finely crushed ore over a bath of solution containing bentonite or other agent which increases the density of the solution. When the density of the solution is properly calibrated, the hematite will sink and the silicate mineral fragments will float and can be removed.

iron ore processing equipment

The mineral processing equipment is of various and different sizes. For the mineral processing equipment, the ore separating machines mainly include feeding equipment, transportation equipment, crushing equipment, grinding equipment, mixing equipment, classification equipment, selected equipment, dewatering equipment, drying equipment, molding equipment and other plants being the major series.

Iron ore processing generally requires the mining of iron ore from either open pit or underground mines; the crushing and grinding of iron ore; the separation of valuable minerals from matrix rock by a variety of concentration steps; and at some operations, the drying, calcining, or pelletizing of concentrates to ease additional handling and refining. The usually used iron ore processing equipment are iron ore jaw crusher, impact crusher, cone crusher, iron ore grinding mill, iron ore separator, iron ore pelletizer, rotary dryer, iron ore screening equipment and so on.

Iron Ore Crushing Plant

Iron ore crushing may be divided into primary crushing, secondary crushing and tertiary crushing. For primary crushing, iron ore jaw crusher are extensively used and nicely received. Impact crusher and cone crusher are typically used right after a jaw crusher, they¡¯re used for additional crushing. Right after crushed by impact crusher and cone crusher, if it really is important, the crushed supplies will likely be sent to a grinding mill for further grinding. The regularly used iron ore grinding mills are iron ore ball mill, trapezium mill, vertical roller mill, super thin grinding mil and so on.
