The ore selected useful elements for iron, sulfur and phosphorus are relatively low, no comprehensive recovery of useful associated elements.
Because the test sample weight limit test using only 5500Oe and 3500Oe two in the magnetic field strength, cylinder surface line speed of 1.2m/s and 1.6m/s, according to -300mm, -60mm, -25mm and the -12+5mm four particle size of ore samples, the contrast test of dry polishing. The final test results are shown in table 1-1.
Through the test of different sizes of dry, for different particle level, can improve all the iron grade of 4.800~5.300%, reduce the grinding quantity 22.65~38.7%, and the recovery rate of the magnetic iron is greater than 98%, that of dry tailings can significantly increase the economic efficiency of enterprises.
