【Abstract】 In the iron ore of Hongpo and sachang on Bajie, limonite is a chief iron-bearing mineral. It ocaupied 95.65% Fe of the total iron in the ore saimple. which constitued 50% each of the two ores. On the basis of magnetic analyses, a high intensive magnetic saparate method was used. For this, weakly—magnetic material, As the process with a voughing, a clearing and two scavenging had been employed, a better result was obtained, The concentrate contained 53.18% Fe,with a recovery of 88.31% and 16.30% Fe in tailing。更多还原
