在浮选过程中,精矿品位和精矿回收率是两个互相制约而又分别要求达到的重要指标。当原矿性质、给矿量、磨矿、分级、搅拌以及药剂等技术操作条件确定后,主要依靠控制浮选设备中矿液面的高低,也就是通过掌握泡沫产品的刮出量来调节。但是,在实际生产中,上述条件是经常变化的,这就 In the flotation process, concentrate grade and concentrate recovery rate are two important indicators of each other constraints, respectively, to achieve. When the nature of the ore, to the ore volume, grinding, grading, mixing and pharmaceutical and other technical operating conditions to determine, mainly rely on the control of flotation equipment in the level of ore surface, that is, by controlling the amount of foam products to adjust the amount of scraping. However, in actual production, the above conditions are constantly changing, and this is
