Methods of test for magnetite for use in coal preparation
選煤用磁鐵礦的試驗方法Magnetite for use in coal preparation - test methods
選煤用磁鐵礦粉試驗方法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。The test results show that the whiteness of high - grade grammite powder can be increas4ed from 72 to 84 by using single high - intensity magnetic separation, and the one of low - grade grammite powder containing carbonaceous materials from 62 to about 81 by using the hims - airflow pulverising - flotation flowsheet
試驗結果表明，採用單一強磁選方法可將硅灰石富礦粉的白度由72提高到84 ；採用強磁選-氣流粉碎-浮選新工藝可將含碳質物的硅灰石貧礦粉的白度由62提高到81左右。Abstract : 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
