由于我矿滤过机所处理的物料过细(-0.074公厘佔80％),矿液较粘(其中有大量合镁矿物,如辉石、陽起石、滑石、透闪石、绿泥石等),使得选矿厂滤过机的生产效率很低,一般仅达到设计能力的80％左右。在1958年我厂生产量不断提高,生产与扩建同时大躍进的情况下,精矿车间所需处理铜精矿相应地增加到235％,但在生产扩建双跃进中,精矿车间所扩建的滤过机未能按时投入生产。因此,过滤效率低,不能适应生产的不平衡现象日愈显得严重。由于滤过

Due to the small amount of material handled by mine filtration machine (-0.074 mm, accounting for 80%), the mineral liquid is stickier (including a large amount of magnesium minerals such as pyroxene, actinolite, talc, tremolite, chlorite Etc.), making the concentrator filtration machine production efficiency is very low, generally only about 80% of design capacity. In 1958, with the continuous improvement of production capacity and the great leap forward in production and expansion, the copper concentrate to be processed in the concentrate workshop increased accordingly to 235%. However, in the mid-production expansion and double-lengthening, the expansion of the concentrate plant The filtration machine failed to put into production on time. Therefore, the inefficiency of filtration and the imbalance that can not adapt to production become increasingly serious. Due to filtration
