我矿区浮选柱原使用帆布袋充气器,虽能达到空气弥散的效果,但因矿浆pH值高,极易结钙堵塞,使用期仅达一个星期左右。在马鞍山矿山研究院的协作下,从1972年开始,进行了水气喷射充气器的小型试验和工业实践,获得了良好的效果。今年以来,在批林批孔运动的推动下,针对生产中出现的问题进行了改进,基本上克服了翻花、喷嘴堵塞和磨损等问题,使水气喷射充气器在生产上得到了应用。我矿区属热液隙充填小型富铜矿床。主要金属矿物为黄铜矿,次为辉铜矿、斑铜矿、其他矿物有黄铁矿、镜铁矿、赤铁矿等;脉石矿物有 I used the flotation column mine bag inflatable bag, although the effect of air dispersion can be achieved, but because of the high pH of the slurry, extremely easy to clogged, the use of only about a week. In collaboration with the Maanshan Institute of Mining, small experiments and industrial practices have been carried out since 1972, with good results. Since the beginning of this year, with the promotion of the “Punch Hole and Hole Punch Campaign”, the problems appearing in the production have been improved, basically overcoming the problems of over-flow, nozzle clogging and abrasion, etc., which have made the application of the gas-jet inflator. My mine is hydrothermal gap filling small copper-rich deposits. The main metal minerals are chalcopyrite, the second is chalcopyrite, bornite and other minerals are pyrite, specular iron ore, hematite, etc .; gangue minerals
