在我国钢铁工业大发展的新形势下,广大矿山工人阶级,为保证矿石原料的充分供应,广泛地掀起了“大打矿山之仗”的热潮。原有的矿山在迅速扩大生产能力,新的矿床也不断被开发利用,矿石的品种、类型逐渐增多。故研究它们的有效处理方法,以适应各种不同生产条件,已是当前的重要任务。 在我国广泛分布的贫铁矿资源中,向来存在着磁铁矿石(俗称青矿)和红铁矿石两大类。前者所含有矿物为磁铁矿,磁性强,可用弱磁场磁选机容易地选出,生产效率高,是易
In the new situation of the great development of China’s iron and steel industry, the general working class of the mine has set off a wave of “fighting the battle of the mines” extensively in order to ensure the adequate supply of ore raw materials. The original mines are rapidly expanding production capacity, new deposits are also being continuously developed and utilized, and the varieties and types of ore are gradually increasing. Therefore, studying their effective treatment methods to adapt to different production conditions has become an important task now. In China’s widespread distribution of iron ore resources, there has always been magnetite (commonly known as green ore) and red iron ore two categories. The former contains magnetite, magnetic, magnetic field can be used weak magnetic separator easily selected, high production efficiency, is easy
