为了充分利用矿产资源,变废为宝,1992年初,由歪头山铁矿劳动服务公司与冶金部马鞍山矿山研究院,在尾矿再选可行性研究和小型试验的基础上,对该矿尾矿再选厂采用以HS—φ1600×8磁力回收机做为粗选作业主要设备的粗精再磨再选工艺流程进行了工业生产调试,取得了明显的经济和社会效益。此项成果已于1992年11月14日,在本钢歪头山铁矿通过由冶金部主持的技术鉴定。
In order to make full use of mineral resources, turning waste into treasure, in early 1992, the Waitoushan Iron Ore Labor Service Company and the Ma On Shan Institute of Mining Research Institute of Metallurgical Department, tailings re-election feasibility study and small-scale experiments based on the tail Mining re-election plant to HS-φ1600 × 8 magnetic recovery machine as the main equipment rougher operation of the fine grinding regrinding re-election process for industrial production debugging, and achieved significant economic and social benefits. The result was passed on November 14, 1992, at Bensou Iron & Steel, Benxi Iron and Steel through the technical appraisal hosted by the Ministry of Metallurgy.
