Iron Ore Processing Flowsheet
Stone crusher is suitable for the soft or hard and extremely hard materials crushing, plastic, are widely used in all kinds of ores, cement, refractories, aluminum every soil clinker, carborundum, glass raw materials, mechanisms, building sand, stone and a variety of metallurgical slag, especially for silicon carbide, corundum, sintered bauxite, the sand jof hard, hard and abrasive wear resistance materials is higher than other types of crusher production effect.
Also known as red hematite ore its chemical formula is Fe2O3, it is a weakly magnetic iron minerals , magnetite can be floating over the good , is one of the main raw material for iron making . The main beneficiation process has re-election , and high intensity magnetic separation or flotation beneficiation process and use a variety , also had a weak magnetic separation after magnetizing roasting process .?Hematite generally use the re-election process , the main jig, centrifugal concentrator , spiral chute, spiral concentrator , shaking , etc. ,
because of its ore processing capacity of small , low- grade ore dressing , low recovery gradually be eliminated later, hematite beneficiation flotation process and the development of strong magnetic separation process , mainly paraffin oxide soap as collector ‘s positive flotation process and electromagnetic flat ring VPHGMSs sorting equipment for the high intensity magnetic separation process . But its sorting technical indicators have not achieved satisfactory results.In recent years , hematite beneficiation achieved considerable development, its main beneficiation process is electromagnetic pulsating high gradient magnetic separator for the strong magnetic beneficiation process on behalf of and in series as the representative of the anti- flotation beneficiation process . In particular, the use of magnetic – flotation process to make some joint hematite mines sorting reached grade iron ore , iron ore recovery satisfaction index .
Magnetite beneficiation process most widely used method of wet and dry joint beneficiation process , mainly on the conduct of the three magnetic ore processed , and then the wet material magnetic separation, magnetic field strength of the selected 400 ~ 1200GS, magnetic roller speed 60 to 320 rev / min, wet material obtained by dehydration of finished iron ore powder , usually iron ore content of 35% by this method after magnetic separation of iron ore powder iron content of up to 68 to 70% , the combined process method , ore utilization up to 90 % less water in the process , save water , reduce costs, reduce pollution, magnetic dust from the dust collecting device will not cause air pollution , this method is a high productivity , good product quality , no environmental pollution creative process method .
Magnetite beneficiation process
Magnetite beneficiation process description: Broken Process: The iron ore hardness greater , and therefore the use of large coarse broken jaw crusher , crusher before adding feeder evenly into the jaw crusher for mineral raw materials , while the screening of ore -75mm +75 mm and two mitochondrial level , +75 mm size fraction into coarse jaw crusher broken ,-75mm grain size into the cone crusher . Grinding process: As the ore hardness greater disseminated fine granularity , the ordinary period of grinding process is difficult to achieve the desired output and monomer dissociation degree , the process uses two grinding processes , reducing fossil situation ore mill efficiency and reduce mudding and caused excessive wear , but also to increase production , to the grinding fineness requirements. Sorting process: sorting process using three permanent magnetic drum separator sorting , some sorting using a magnetic separator,
Sec sorting using a magnetic separator rougher featured a magnetic separator, concentrate grade of 63 in order to achieve the above requirements . The sorting process adds demagnetization process to take off after the magnetic minerals brought their own magnetic flux to avoid affecting the concentrate grade improvement.
