The ore needs to be broken to meet the requirements of feeding before flotation. Flake graphite minerals mostly use stage grinding stage flotation process flow [28]. As shown in Fig. S1, the grinding time is determined to be 6 min after preliminary exploration. The experiment is divided into the roughing stage and beneficiation stage.Web

After the 4 min flotation process, the recovery rate of graphite was above 92.7%, while the floatability of cathode materials was poorer, with a recovery rate ranging from 8.1% to 31.0%. The differences in recovery rates among different cathode materials may be due to differences in their wettability and particle size.Web
