The Use of Magnetite
Magnetic not only has important applications in modern medicine, such as magnetic resonance imaging technology, commonly known as magnetic resonance CT (computerized tomography), as well as the MCG and magnetoencephalography applications, but also a long history. Medicinal magnetite magnet alias Kuroishi, Tsz stone and spiritual magnet, magnet, suction needle stone.
Magnetite Iron Beneficiation Process
Mining the ore first preliminary broken jaw crusher broken to a reasonable degree of fineness through the hoist to the mining machine into the ball mill ball mill grinding, grinding of the ore. After the ball mill grinding the ore fines into the next process: classification. Spiral classifier With the different proportion of the solid particles and the speed of the principle of precipitation in the liquid ore mixture, washed and graded. After a magnetic separator, washed and graded mineral mixture, due to the different variety of minerals than the susceptibility through magnetic force and mechanical force the mixture of magnetic material separated to.
Separated from the minerals and other substances into the flotation machine, adding different drugs depending on the mineral characteristics, making the magnetic separator after the preliminary separation of mineral particles. Minerals to be separated, because it contains a lot of
Preliminary enrichment of the water, subject to the concentrator, and then through the dryer to dry, to dry minerals.
magnetite beneficiation process
Magnetite Ore Processing Method
Ore blending weight assigned amount of magnetite powder particle size of less than 10mm, less than 15% moisture of 0-8% of the pulverized coal into the rotary kiln; magnetite iron ore fines in the same rotary kiln drying, magnetization arsenic removal, desulfurization process, the speed of the rotary kiln for 0.8-1.5 rev / min; rotary kiln calcination zone temperature to 800-850 ° C, the temperature of the drying area 350-0 ℃.
After baking mine water cooling; cooling Classifier return sand separation with magnetic pulley, overflow via concentrate pump to the wet weak magnetic separator, the magnetic part of the final product of iron fine mine. Iron ore fines ore of low iron, high grade arsenic sulfur impurities brown coal blending, dry roasting, the magnetization removing arsenic and sulfur impurities in the same kiln body.
Magnetite Mining Equipment
Magnetite beneficiation equipment equipment: jaw crusher, hammer crusher, roll crusher, impact crusher, Park, cone ball mill, high frequency screen, Spiral very, flotation machines, mining the mixing drum feeder concentrator, mine hoist, mine conveyors, pre-watering Handicap, spiral chute, ore dressing shaker, washing machine and other equipment.
