1/5/2020· Under the same grinding and magnetic separation conditions , magnetic separation was performed for the untreated and treated samples, and the influence of MPP on the magnetic separation was
1/8/2020· Results show that iron concentrate with iron grade of 68.31% at a recovery of 96.34% can be obtained in the magnetic separation concentrate, and manganese concentrate with manganese grade of 33.70% at a recovery of 86.83% can be obtained in magnetic
20/4/2017· Present Practice and State of Development. The largest development in the iron ore industry, using magnetic concentration, is at the plants of Witherbee, Sherman Co. at Mineville, N. Y., where about 1,200,000 tons of crude ore were mined and separated in 1916. The dry process of separation is used.
R.J. Holmes, in Iron Ore, 2015. 9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe to 15% Fe and oxidized iron ore of only about 10% Fe to 20% Fe (oxidized iron ore
Magnetic separation using wet high intensity technique has become one of the most suitable methods for recovery of iron from low grade ores 6, due to its better separation efficiency as compared ...
paramagnetic minerals such as iron and magnetite. High intensity magnetic separators generally have field strengths of 10 to 20 kilogauss. These separators are used to treat weakly magnetic minerals, such as hematite. Magnetic separators are commonly classified into two broad groups, namely, wet and dry based on their usage.
Effect of feed size fraction on the concentrate assay and metal recovery using high intensity magnetic separator. The size labels are: 1 for 500+20 μm, 2 for 350+20 μm, and 3 for 150+20 μm
providing good sensitivity for the majority of elements. A typical iron ore analysis should include a loss on ... All magnetite ore bodies will require some magnetic separation investigation. Tests we regularly perform include: ... Iron ore hematite, magnetite, goethite, itabirite Nickel laterite sulphide ores
4/10/2018· Low intensity separators use magnetic fields ranging between 0.1 Tesla to 0.3 Tesla. Low intensity techniques are normally used on magnetite ore as an inexpensive and effective separation method. High intensity separators employ fields as strong as 1 Tesla to 2 Tesla.
16/1/2017· In examining the results of separation, we find that the heads compose one half of the original material by weight, and carry 67 per cent, of iron, or 92.5 of magnetic oxide, equal to 46.3 out of the original 48.3 in the crude ore, while the tails contain the remainder, which is 2 per cent, of magnetic oxide out of the original 48.3 in the crude material; but this 2 per cent, is 4 per cent, of ...
