山东省福山铜矿选矿厂是一个处理铜硫矿石的选矿厂。今年,我们在矿党委的领导下,团结一致搞四化,革新挖潜创新水平,一季度在原矿品位只有0.5左右的情况下,回收率和精矿品位分别达到93.64%和21.21%,比去年同期(原矿品位0.716%)提高了4.96%和5.03%,精矿品位由原来的11级品晋为3级品,创本矿历史最高记录,达到了同类企业的先进水平。我们的主要做法是:一、改革浮选工艺流程针对选矿回收率和精矿品位上不去的问题,我们组织了干部、技术员和操作工对投产以来的生产情况作了全面的分析和总结,在实验室进行了上百次流程条件试验和现场流程考察,找出了指标升降规律和生产薄弱环节,改革了浮选工艺流程,把原来粗、扫选用的6A 浮选机10槽增加到16槽,全流程浮选时间由原来的14分
Fukuyama Copper Concentrator, Shandong Province, is a beneficiation plant dealing with copper and sulfur ore. This year, under the leadership of the coal mine party committee, we unite to pursue the four modernizations and tap the potential for innovation. In the first quarter, only 0.5 or so of the ore grade achieved a recovery of 93.64% and a concentrate grade of 21.21%, up from the same period of previous year (0.716% raw ore grade) increased by 4.96% and 5.03%. The grade of concentrate was changed from 11 grade to 3 grade, creating the highest record in this mine and reaching the advanced level of similar enterprises. Our main approach is: First, the reform flotation process In view of dressing recovery rate and concentrate on the problem, we have organized cadres, technicians and operators of the production has been put into operation a comprehensive analysis and summary, Hundreds of tests on the process conditions and on-site process were conducted in the laboratory to find out the regularity of the movements and weak points in the production. The flotation process was reformed and the original 10-slot of the 6A flotation machine used for scanning was increased to 16 Slot, the whole process flotation time from the original 14 minutes
