After ball mill grinding of ore fines into the next process: classification.
This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a target size required for physical separation or chemical extraction are returned to the crushing or the grinding circuit.
The former Soviet Union Almak lead-zinc ore processing plant uses this process to obtain higher indicators than the priority flotation process, lead concentrate grade increased by 10%, zinc concentrate grade increased by 4.5%, the comprehensive utilization rate of the ore from 75.4% to 83.7%, labor productivity caught twice as high, China's ...
