铁矿石的精料入炉,是充分利用铁矿资源,节省焦煤用量,挖掘冶炼潜力,加速钢铁工业发展有效措施。贯彻好精料方针,往往采用不同手段,其中,主要用选矿方法来提高铁的品位。选矿方法的使用还可以扩大铁矿资源和综合利用。几年来,我们对昆明钢铁厂所属各矿 Iron ore concentrate into the furnace, is to make full use of iron ore resources, saving the amount of coking coal, mining smelting potential and speed up the development of the iron and steel industry effective measures. Implementation of good concentrate approach, often using different means, of which the main beneficiation method to improve the quality of iron. The use of beneficiation methods can also expand iron ore resources and comprehensive utilization. In recent years, we have all the mines owned by Kunming Iron and Steel Plant
