The poor recovery of molybdenum compared to copper can be the result of low collision efficiency, poor froth recovery and selective drop back from the froth phase and possibly as the carrying capacity is exceeded.
We selected a spray nozzle which generates water drops of this size distribution, and evaluated the water drop dia sprayed from the nozzle and the collision efficiency of paint mist against water drops, which is explained in the next chapter.
Figure 7 shows the concept of collision efficiency of water drops and paint mist.

The collision efficiency is readily obtained from the bat performance test described above, and is found from the ratio of the ball rebound speed to the ball inbound speed.
