Dry Magnetic Separator Magnetic Separator Working. If the production costs such as the ore grinding, magnetic separation and the wet separation tailing processing is 30 yuanton, one set of the pat ented product can save the production costs of about 3-9 million yuan. under the condition of the same amount of mining, the output of the iron concentrate basically remains.
Magnetic separation of weakly magnetic iron mineral fines in the form of flocs, which is termed Floc Magnetic Separation FMS process, has been studied in the present work, in order to find a substitution for high-intensity or high-gradient magnetic separators to treat the ores with weakly magnetic iron minerals in the fine size range.
Jun 21, 2019 Abstract High-phosphorus oolitic iron ore, treated by suspended ash magnetic roasting, contained 42.73 iron mainly present as magnetite and 0.93 phosphorus present as collophane. Low-intensity magnetic separation LIMS was combined with reverse otation to increase the iron and reduce the phosphorus contents of the roasted product.
