从炼铁工业发展讨论我国铁矿选矿发展方向

On the Development Orientation of China's Iron Ore Beneficiation in View of Its Iron-making Industry Development Actualities

论述了我国铁矿石、铁、钢产量快速发展 ,国内高炉炉料铁含量快速提高 (已达到 5 6 %～ 6 0 %) ,国外优质铁矿石大量进口 ,而我国国内铁精矿仍处于铁品位较低、SiO2 杂质高的状态。目前不少钢铁企业都愿意多吃优质进口铁矿石 ,把国内铁矿山当成包袱 ,如此发展下去 ,将直接影响我国现有铁矿山的可持续发展 ,也会影响到铁矿山 2 0多万职工的就业及社会稳定。讨论了这种形势下 ,我国铁矿选矿工业发展的方向、对策及今后应注意的若干问题。

Both China's iron ore,iron and steel output and the iron content in domestic blast-furnace burden (up to 56%～ 60%) increased rapidly.Foreign fine quality iron ore is imported on a large scale while domestic iron concentrate still has low iron grade and high SiO 2 content.Not a few iron and steel enterprises prefer to use more imported fine quality iron ore so as to achieve a best benefit from blast-furnace iron making.Domestic iron mines are seen as something of burden and the sales proportion of domestic iron concentrate is gradually decreased.If things go on lik this,the sustainable development of the existing domestic iron mines will be directly affected,so will be the existence of over two hundred thousand workers and staff members of iron mines.The paper discusses how to develop China's iron beneficiation industry under such conditions and points out its development orientaton,countermeasures and some issues needing attention in the future.
