复杂硫化矿的特点在于有用矿物的结构复杂。对处理这种矿石的各个浮选回路的任何性能评价都应该包括对有用矿物不完全解高度的影响分析。在某座处理细粒级方铅矿、闪锌矿和脉石矿物主要是黄铁矿的选厂中的浮选作业平衡粒度分析中取一些样品，利用QRM*SEM系统对4个或7个粒级进行解离度测量，测得的结果表明，在浮选结料中，方给矿的解高度不到40％，闪锌矿村解离量不到60％。最终精矿主要是由有用矿物和硫化铁的连生体组成，还有少量但很重要的解离硫化铁。利用从初始平衡和解离度测量中获得的分级矿物流，可达到一个人满意的解离平衡。这样可检测出解离度对浮选剂性能的影响，不仅是对整个回路的，还有对租选、扫选和精选阶段的。在锌回路中，还可评价出再磨磨机的作用。在给回路中，方给矿的回收率受到未解高铝颗粒回收率的影响。解离方铁矿的回收率在所有位级中都超过95％。而未解离方错布的回收率在38μm以下时大于85％，在38μm以上时锐减．在铅浮选回路的各个阶段中，对解离的和未解离的方铅矿性能检测表明：解离的和未解离的方铅矿颗粒在粗选和扫选阶段的回收率高，但在最终两段精选中回收率很低。解离闪锌矿的性能在其粒度大于38μm的情况下减弱，但在铅回路中所观察到的情况同样适用于锌回路。?
Complex sulfide ore is characterized by the complex structure of useful minerals. Any evaluation of the performance of each flotation circuit handling such ores should include an analysis of the effects of the incomplete solution of useful minerals. Some samples were taken from a flotation job-balance-particle-size analysis of a flotation site dealing with fine-grained galena, sphalerite and gangue minerals, mainly pyrite, using a QRM * SEM system on four or seven Particle size of the dissociation measurements, the measured results show that in the flotation feed, the side to the mine solution height less than 40%, sphalerite mine dissociation less than 60%. The final concentrate is mainly composed of a symbiotic body of useful minerals and iron sulfide, with a small but significant amount of dissociated iron sulfide. Satisfactory dissociation equilibrium can be achieved using fractionated mineral streams obtained from initial equilibrium and dissociation measurements. This will detect the impact of dissociation on the performance of the flotation agent, not only for the entire circuit, but also for renting, scanning, and selecting phases. In the zinc circuit, but also evaluate the role of grinding mill again. In the feed-back circuit, the recovery of square ore is affected by the unrecovered high alumina particle recovery. The recovery of witherite is over 95% at all levels. However, the recovery rate of the undissociated fabric was more than 85% when the recovery was less than 38μm, and sharply decreased when the recovery was not less than 38μm. Examination of the dissociated and undissociated galena at various stages of the lead flotation loop showed that the recovery of both dissociated and undissociated galena particles during the roughing and scavenging stages was high, But the recovery rate is very low in the final two sections of the selection. The performance of the cleaved sphalerite diminishes with its particle size greater than 38 μm, but the same observations made in the lead circuit apply equally to the zinc circuit. ?
