Magnetite Iron Ore Mobile Beneficiation Plant

Project Background

Magnetite iron ore beneficiation plant flow sheet design and option selection should be tailored to the magnetite ore comminution and liberation characteristics.

Magnetite iron ore beneficiation plant flow sheet design and option selection should be tailored to the magnetite ore comminution and liberation characteristics. For fine-grained ores the addition of a third grinding stage which utilises energy efficient stirred milling benefits the economics in two ways: reducing the amount of material that need to be fine ground and grinding at high energy efficiency. The application of HPGR technology significantly reduces the energy consumption compared to AG milling. A ¡®synergy¡¯ of HPGR and primary pebble milling, as proposed for Option 4, can result in a very effective circuit from a capital and operating point of view with HPGR working in open circuit feeding the primary pebble mill which in addition to grinding, generates grinding media (pebbles) for the secondary pebble milling circuit. The product from the primary pebble mill is much finer than what can be practically obtained from a closed HPGR circuit and thus the tail rejection at the RMS is higher which significantly reduces the duty of the following pebble milling stage.

Magnetite features high hardness, so large Jaw Crusher will be adopted in the rough crushing process. In the whole magnetite crushing plant, vibrating feeder should be installed in front of Jaw Crusher, raw material are uniformly fed into Jaw Crusher, in the same time vibrating feeder will classify the raw mineral into +75mm and -75mm two fractions. The +75mm fraction will be transported into Jaw Crusher for rough crushing and -75mm fraction will be transported into Cone Crusher for crushing.

magnetite iron ore grinding mills

For magnetite features high hardness and very fine grained disseminated grain size, adopting the ordinary one-section grinding process is hardly to achieve the due production and monomer dissociation degree. So the magnetite grinding technology adopts the two-section grinding process. The magnetite two grinding process not only decreases the happening frequency of mineral argillization when mineral is ground and grinding machine low efficiency, but also could increase the volume of production, to achieve the required ore grinding fineness.

Magnetite Iron Ore beneficiation process includes:gravity separation,flotation,strong magnetic beneficiation or mix several beneficiation process,and another process is magnetization roasting and then weak magnetic separation. The early Magnetite beneficiation mostly used the gravity separation process,and the main machines are: jigger,centrifugal separator,spiral chute,spiral washing machine,shaking table etc. Because some other beneficiations production capacity was small,the grade after processing was low,recovery ratio is low and then was dumped as time goes on. Later as the Magnetite beneficiation developing,the flotation process ans high intensity magnetization process. It mainly use oxidized paraffinum sodium salt as the collector for flotation and electromagnetic strong magnetic separator as beneficiation equipment for strong magnetic separator.
