铁矿石在磨矿之前,用磁选法预先进行分选,可以剔除废石,提高入选的铁品位,减少磨矿量,降低能耗,是选厂挖潜、增产增收的有效方法。我国已有不少的铁矿选厂,如金岭、程潮、板石沟、大石河、水厂、綦村、玉石洼、符山、梅山、小吴营、午汲等,都应用了这项技术,获得了显著的经济效益。漓渚、金山店等选厂用这项 Prior to grinding iron ore, pre-sorting by magnetic separation method, you can remove the waste rock, improve the selected iron grade, reduce the amount of grinding, reduce energy consumption, it is an effective way to plant potential, increase production and income. There are many iron ore processing plants in our country, such as Jinling, Chengchao, Banshigou, Dashihe, waterworks, Quncun, Jadewave, Fu Shan, Meishan, Xiaowuyin, Wuji etc. This technology has gained significant economic benefits.
