  1. 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

    用重選法從劉嶺鐵礦磁選尾礦中回收鐵礦物，可獲得鐵品位大於20 %的含鐵物料，用此物料代替部分粘土質原料生產硅酸鹽水泥，使礦山尾礦排放量減少至43 . 52 % ，鐵的回收率由70 . 89 %提高到84 . 62 % ，並且減少了水泥生料配料中鐵礦粉的用量，降低了生料粉磨能耗。
