梅山铁矿由于原矿含磷较高,而在选矿生产中一直无降磷措施,因此铁精矿中磷也很高,适应不了市场需要,也不能满足公司炼钢生产,严重制约了矿山的生产。梅山铁矿与鞍山冶金设计研究院、马鞍山矿山研究院、赣州冶金研究所等科研单位合作,经多次试验研究,最后采用“浮选—弱磁选—强磁选”的新工艺来降低铁精矿中的磷。1996年投资4000万元,建成了“浮—磁—磁”的降磷生产工艺。经过试生产后,1999年4月全线投入生产。铁精矿中的磷从0.40%～0.60%降至0.25%以下,基本满足了炼钢生产,也拓宽了铁
Due to the high phosphorus content of ore in Meishan Iron Mine, there is no measure to reduce phosphorus in ore dressing production. Therefore, the phosphorus in iron concentrate is also very high, which can not meet the needs of the market and also can not satisfy the Company’s steelmaking and seriously restrict the production of mines . Meishan Iron Mine and Anshan Metallurgical Design and Research Institute, Ma On Shan Institute of Mining, Ganzhou Institute of Metallurgy and other scientific research units, after many pilot studies, the final use of “flotation - weak magnetic separation - strong magnetic separation,” the new technology Reduce iron in iron concentrate. In 1996 invested 40 million yuan, built a “float - magnetic - magnetic ” of the phosphorus production process. After trial production, in April 1999 all the production lines. Iron concentrate from phosphorus 0.40% ~ 0.60% down to 0.25%, basically meet the steel production, but also broaden the iron
