(一) 生产概况大龙山选厂手选和光电选废石中丢失的单体块钨一直未得到解决。为此,我矿技术人员于1979年提出“光电机后面加跳汰回收废石中丢失块钨的专题报告”。后经江西省冶金局定为1980年矿山科研重点项目,并指定江西有色冶金研究所负责,1981年底,该所用AM型350×1000毫米双系列旁动隔膜跳汰机进行工业试验,1982年1月12日一次试车成功,效果良好。至6月29日止,共开车1797小时,收回单体块钨1019.27公斤,平均每小时收回块钨0.567公斤,生产能力2.5(吨/时·
(I) Production Overview The monolithic tungsten lost in the selection and selection of large-scale Longshan process plants has not been solved yet. To this end, I mine technicians in 1979 put forward “photojournal behind the jig recovery of waste lumps of tungsten in the special report.” After Jiangxi Provincial Metallurgical Bureau was designated as mine research project in 1980 and designated Jiangxi Institute of Nonferrous Metallurgy, by the end of 1981, the use of AM-type 350 × 1000 mm double series of bypass membrane jig for industrial tests, 1982 1 A successful trial on January 12, the effect is good. As of June 29, a total of 1797 hours were driven to recover 1,019.27 kilograms of monolithic tungsten with an average of 0.567 kilograms of block tungsten recovered per hour, with a production capacity of 2.5 tons per hour
