China has abundant of Iron Ore reserves, estimated at about 57.172 bn. tonnes. However, lean ore accounts for about 97.72% and the average grade is 32.67% only. The raw material condition compelled Chinas research to develop the beneficiation technology vigorously. And, after years of investment in manpower, material and financial resources, led to a breakthrough in development of new technology for beneficiation of hematite-type iron ore. Hematite ore is mainly concentrated in northeastern China Anshan, where our joint venture company Anshan Metallurgical Design& Research Institute is located. With years of experience garnered in design and construction, technology for beneficiation of hematite& magnetite type iron ore has matured. The basic process for hematite beneficiation involves Crushing Grinding Magnetic separation Gravity separation High gradient magnetic separation Floatation / Reverse floatation. The beneficiation of the iron ore is from grade of 32% to 68%. In the past two decades, many projects, as well as feasibility studies on Mining and beneficiation plant, have been realized, both in China and overseas. Representative projects are as follows: 7 MTPA capacity of Gaocun beneficiation plant of Maanshan steel ltd., 5 MTPA capacity of Heshangqiao beneficiation plant of Maanshan steel ltd., Tailing Dam of Tarja Abu Maluku Iron Ore Beneficiation Plant, Indonesia; Feasibility study for Ispat Iron Ore Beneficiation Project of 2.1 MTPA in India, Feasibility study for Erdemir Hasancelebi Iron Ore Beneficiation Plant of 11 MTPA, in Turkey etc.
