coarse grinding and rougher flotation stage with minimal grinding energy costs as against the usual practice of single stage grinding in the case of many ores. A final concentrate of 8.97% weight recovery with 5.80% ash and 92.13% fixed carbon could be achieved. Key words: low grade graphite, liberation, froth flotation, regrinding, refractory. 1.
How to determine the stage and flow path of flotation
After flotation, it is not necessary to carry out grinding again. This flotation process is also called one stage flotation process. For example, some crystalline mineral needs to be ground under 0.074mm to reach monomer separation. This kind of mineral is fine disseminated even, which is also suitable for one stage flotation process.

The details of the optimal three-stage grinding flotation process are shown in Figure 2. The grinding fineness of the first, second and third stage were −74 μm 40%, −74 μm 87% and −74 μm 92%, respectively. After the grinding process, multi-stages of cleaning were carried out to remove the liberated gangue particles as much as possible.
