Experimental Study on Dry Pre-concentration and Wet Magnetic Separation of an Ultra Poor Magnetite Ore
摘要
Abstract
The dry pre-concentration tests on crashed sample and three stages wet magnetic separation tests on concentration of pre-concentration tests under appropriate grinding fineness were carried out aiming at one ultra poor magnetite ore.The results showed that the optimal particle size for dry pre-concentration tests is-3 mm.Under the condition of belt speed of 80 r/min,magnetic field intensity of 318.4 kA/m,pre-concentration is able to upgrade the crashed products to 19.98％ iron grade and 50.64％ recovery with 80.03％ tailings discarding rate.The milling cost before subsequent wet magnetic separation can be greatly reduced.For wet magnetic separation,the iron grade was 67.15％,the operating recovery was 78.20％,and the tailings iron grade was 5.66％.关键词
