用定量电视显微镜720图像分析仪,研究了1979年9月取自布伦斯威克矿冶公司选矿厂第二段锌回路的试样,以确定每排浮选槽中,闪锌矿、方铅矿和黄铜矿的矿物解离度与粒度分布以及金属平衡。与1977年所采试样的相似数据结果的比较表明,与相同浮选槽相比,闪锌矿的回收率较好;与其它槽相 Using a quantitative television microscope 720 image analyzer, a sample of the second loop of the zinc recovery from the Brunswick Mining and Metallurgical Corporation concentrator in September 1979 was studied to determine the concentration of sphalerite in each row of flotation cells Mineralization and particle size distribution and metal balance of lead and chalcopyrite. A comparison with the results of similar data from the samples taken in 1977 showed that sphalerite recovery was better than that of the same flotation cell;
