冶金部马鞍山矿山研究院与鞍山冶金矿山公司矿山研究所协同,在研究所试验厂对齐大山贫赤铁矿25～0毫米粉矿进行了工业试验,据50个班的连续生产指标统计,获得了铁精矿品位65.04％、铁回收率为78.36％的好成绩,达到了冶金部对齐大山矿石选矿试验要求的“65、75”技术指标。试验采用的工艺流程是弱磁选-强磁选-弱酸性介质正浮选联合流程。试验考查了该工艺流程对齐大山矿石英
The Ma’anshan Mining Research Institute of the Ministry of Metallurgy, in collaboration with the Institute of Mines of Anshan Metallurgical Mine Company, carried out industrial tests in the Institute of Experimental Plants aligned with the 25 ~ 0 mm fines of the mountain hematite. According to the continuous production index statistics of 50 classes, Iron concentrate grade 65.04%, iron recovery rate of 78.36% good results, met the Ministry of Metallurgical Alignment Dashan ore dressing test requirements of “65,75” technical indicators. The process used in the test is weak magnetic separation - strong magnetic separation - weak acid medium is the flotation joint process. The test examines the process alignment Daishan ore Quartz
