近年来,在选煤生产中浮选的重要性已日趋明朗,并为选煤工作者所重视。实践证明,在选煤厂抓好了煤泥浮选这一环节,不仅能提高全厂的精煤回收率,减少低灰分煤泥外流,而且使洗水浓度大幅度下降,改善了跳汰、脱水、浓缩和沉淀等各个环节的工作。因此,我国新建的炼焦煤选煤厂就全部设有浮选作业,原来没有浮选作业的老厂,也逐步增设了浮选设备。如以1965年浮选车间和浮选机总台数 In recent years, the importance of flotation in coal preparation has become increasingly clear, and is valued by coal preparation workers. Practice has proved that at the coal preparation plant grasp the flotation coal slime this link, not only can improve the recovery rate of clean coal plants to reduce the outflow of low-ash slime, but also significantly reduce the concentration of washing water to improve the jig, Dehydration, concentration and precipitation and other aspects of the work. Therefore, China’s new coal-coking coal preparation plant all equipped with flotation operations, the original flotation operations of the old plant, but also the gradual addition of flotation equipment. Such as the 1965 flotation plant and the total number of flotation machines
