Study on Improving of the Iron Concentrate Grade Index by Centrifuge

Abstract:

In this study, the main aims were to iron-increasing and silicon-reduction of the iron concentrate by using centrifuge separating technology. Experimental studies were carried out on high-silica ferromagnetic iron concentrate in Dahongshan samples, which contain 50% of iron and 15% silica. Through the experiment, it chooses SLon1600 to iron-increasing and silicon-reduction of the iron concentrate. The optimum condition is pulp density of 20%~25%, feed speed of 1.99t/h, rinse water of 6.4t/h and flushing water of 10.22t/h. The iron concentrate which the grade of Fe is 62.36% and the recovery of 80.47% is obtained and the grade of silica reduce from 14.48% to 5.4%. High-quality iron concentrate is obtained, which has a better effect.
