我矿选矿车间浮选用的是6A型机械搅拌式浮选机,原矿经一次粗选、一次扫选和四次精选后,选出品位含P_2O_530％的精矿。尾矿品位为1.5％左右,在原设计和以往的生产实践中一直作为“废物”扔掉。 1970年在用原浮选流程的尾矿进行浮选柱气水合流充气器性能试验时,发现尾矿有经过再选而制得中品位磷矿粉的可能性。车间领导立即抓住这个苗头,召开了“三结合”会议,在批林整风运动的推动下,狠批了反动的唯心论的“先验论”和“生产定型”,“技术到顶”等错误思想,提高了觉悟。从
I used mineral processing plant flotation is 6A mechanical agitation flotation machine, crude ore after a rough selection, a sweep and four selected after the election, select the grade P_2O_530% of the concentrate. Tailings grade of about 1.5%, in the original design and production practices in the past has been as “waste” thrown away. In 1970, when the flotation column gas hydration inflator performance test was carried out on the tailing of the original flotation process, it was found that the tailings could be re-selected to produce medium grade rock phosphate. The workshop leader immediately seized this sign and held a “three-in-one” meeting. Under the impetus of the campaign of rectifying forests and rectifying the wind, he severely criticized the erroneous ideas of “transcendentalism” and “production stereotyping” and “technology reaching the top” of reactionary idealism.
