摘要:
鲕状赤铁矿有用矿物嵌布粒度细，磨矿成本高，属于典型难选铁矿石。磁化焙烧-磁选工艺是分选此类难选铁矿石的有效方法，研究了不同冷却方式对磁化焙烧矿的磨矿性能产生的影响.鲕状赤铁矿进行磁化焙烧后分别隔绝空气密闭冷却、水淬及空气中自然冷却，进行粒度筛析和磨矿试验.发现焙烧后矿石粒径变粗，从原矿的平均粒径为0.069 9 mm至密闭冷却、水冷和自然冷却焙烧矿的0.088 2 mm、0.084 3 mm、0.087 0 mm.相同磨矿条件下，原矿、密闭冷却焙烧矿、水冷焙烧矿和自然冷却焙烧矿-0.045 mm含量分别为84.89%、83.89%、76.51%、77.14%.表明磁化焙烧使鲕状赤铁矿变得更为难磨，密闭冷却时磨矿效果最佳，自然冷却次之，水冷最差.
Abstract:
Oolitic hematite is a kind of typical refractory iron ore because of its fine inlay granularity and high grinding costs. Magnetizing roastingmagnetic separation process is an effective process beneficiation to this kind of refractory iron ore. The effects of the grinding by different cooling modes were analyzed. After magnetization roasting, oolitic hematite were cooled in closed system (isolated from air), water and air, respectively, followed by a particle size sieve analysis and grinding test. The results indicate that the average diameter of particle increases from 0.069 9 mm to 0.088 2 mm(closed cooling), 0.084 3 mm(water cooling) and 0.087 0 mm(natural cooling) after roasting; under the same grinding conditions, and -0.045 mm contents are 84.89%, 83.89%, 76.51% and 77.14% respectively in crude ore and roasted ore after closed cooling, water cooling and natural cooling. It is concluded that magnetizing roasting made the oolitic hematite more difficult for grinding；the grinding effect of oolitic hematite is best in closed cooling, followed by natural cooling and then water cooling.
