This test verified that the introduction of ultrasonic-assisted flotation can simplify the cleaning process of graphite. Technological graphite flotation processing flow-sheet using ultrasonic treatment is shown in figure 3. Owing to the optimal flotation effect being found at an ultrasonic power of 1600 W, the power of 1600 W was used in the ...

Figure 151 is the flow sheet of one section of the Cananea Consolidated Copper Co. mill as it was in 1929. This is a simple straight-flotation process that replaced an earlier combined gravity and bulk-flotation method. Table 58 summarizes the differences between results obtained from the earlier and later methods.
