为了使齐大山选厂按弱磁-强磁-弱酸性浮选工艺流程进行稳妥的改造,马鞍山矿山研究院先后于1981年和1982年,又对该流程进行了生产验证试验和回水利用试验,均获得成功。冶金部于1982年6月22～26日,在北京召开了审查会议,对上述两项试验报告给予审查通过。至此,为齐大山选厂改造所安排的试验任务已全部完成。弱磁-强磁-弱酸性浮选工艺流程生产验证 In order to make Qidashan processing plant according to weak magnetic - strong magnetic - weak acid flotation process for the safe transformation, Maanshan Institute of Mining has in 1981 and 1982, and the process of production verification test and back to water use test , Have been successful. The Metallurgical Department held a review meeting in Beijing from June 22 to June 26, 1982, to review and approve the above two test reports. At this point, the task of arranging for the renovation of QiDa Mountain has been fully completed. Production Verification of Weak Magnetic - Ferromagnet - Weak Acid Flotation Process
