根据实验室对鞍钢齐大山红铁矿研究的成果,1978年末,由鞍山冶金矿山公司矿山研究所、鞍山矿山设计院、北京矿冶研究院、鞍山钢铁学院、广州有色金属研究院等单位协作,在鞍钢选矿试验厂进行了磁一重和重-磁联合流程的工业试验,取得了精矿品位65％,铁回收率为75％的选别指标,达到了国家规定的要求,使我国红铁矿选矿技术有了新的突破。本文就工艺中的一些问题提出分析和讨论。
According to the laboratory's research on the Anshan Iron and Steel Qidashan red iron ore, by the end of 1978, Anshan Metallurgical Mining Company Institute of Mining, Anshan Mining Design Institute, Beijing Institute of Mining and Metallurgy, Anshan Iron and Steel Institute, Guangzhou Nonferrous Metal Research Institute and other units, In Ansteel beneficiation test plant carried out a magnetic-heavy and heavy-magnetic combination process of industrial tests, has achieved the concentrate grade 65%, iron recovery rate of 75% of the sorting index, meet the requirements of the state, so that China's iron ore Beneficiation technology has a new breakthrough. In this paper, some problems in the process of analysis and discussion.
