How chose ore crushing equipment for Iron Ore Mining and Beneficiation





For Iron Ore Beneficiation Plant, whether it’s hematite or magnetite iron ore, MEPC is capable of undertaking the projects including engineering, design, equipment supply, supervision, training and maintenance on EPS, EPC or Turnkey basis with capacity from 0.1 to 18 million TPA as required by the Client.

China is abundant of Iron Ore reserves, estimated at about 57.172 bn. tones.  However, lean ore accounts for about 97.72% and the average grade is 32.67% only. The raw material condition compelled China’s research to develop the beneficiation technology vigorously. And, investment in manpower, material and financial resources, Grinding mill 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.

Iron ore beneficiation process

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 ROM iron ore is up graded from 32% to 65% – 68% in Fe content.

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.

India’s Steel Authority of India Iron Mining Equipment is seeking bids from global companies to construct a 12.5 million-ton-per-year iron-ore beneficiation plant on a turnkey basis at its Guam mines in the state of Jharkhand. The plant is part of the company’s plan to double the iron-ore production capacity of Gua to 10 million tons per year. The company is also close to finalizing a collaboration agreement within the next two months with iron ore mining equipment to construct a 12 million-ton Greenfield steel plant at Bokhara.
