刘岭铁矿尾矿综合利用的研究

用重选法从刘岭铁矿磁选尾中回收铁矿物，可获得铁品位大于２０％的含铁物料，用此物料代替部分粘土质原料生产硅酸盐水泥，使矿山尾矿排放量减少至４３．５２％，铁的回收率由７０．８９％提高到８４．６２％，并且减少了水泥生料配料中铁矿粉的用量，降低了生料粉磨能耗。

Investigation on the Tailings Comprehensive Utilization of Liuling Iron Mine

An iron-containing material with an iron grade of over 20% can be recovered from magnetic separation tailings of Liuling Iron Mine by gravity method.This material can be used instead of partial clayey material to produce portland cement so as to reduce the mine tailings discharge amount to 43.52%,to raise the iron recovery from 70.89% to 84.62% and to reduce the iron ore powder consumption in raw cement mixture and the energy consumption of raw material grinding.
