Magnetic Separation Method Magnetic Engineering
the beneficiation of low grade iron ores is being accomplished using a number of different techniques, see u.s. pat. nos. 3,337,228 and 3,502,271 including washing, jigging, heavy media separation, flotation and magnetic separation. ore concentrates thus obtained typically contain from 69% of iron and between 10% of silicon dioxide.oct 23, 2020 the fine sand particles pass through the iron mesh and remain behind. the method of sieving is also used to separate similar objects of different sizes. the cashew nuts of different sizes are separated in cashew nut factories by the process of sieving. magnetic separation magnetic separation means separation of a mixture by using a magnet.
