摘　　要：风化矿是铁矿开采中剥离出的低品位表外矿,难以选矿利用。然而其具有一定吸水性和离子交换性,同时含有少量铁可作为球团铁品位的补充,因此风化矿有作为球团粘结剂的潜质。风化矿微粉经改性后与其它粘结剂以一定的比例混合用于制作铁矿球团复合粘结剂,既能减少常规球团矿工艺中膨润土粘结剂的用量,又可实现风化矿废料的综合利用,经济和社会效益显著,工业化应用前景广阔。Weathered ore is the low grade off-surface iron ore which is difficult to be utilized.However,the weathered ore has the potential to be used as a pellet binder,due to its hydroscopic property,ion exchange property and concentration of iron.Therefore,the modified weathered ore powder can be used as a composite pellet binder by mixing with other binders at the certain ratio.The composite binder can not only reduce the amount of bentonite in the pelletizing process,but also reach the comprehensive utilization of weathered ore,which has significant economic benefits and value in industrial applications.
