Literature quest and survey on graphite beneficiation
The basic steps of beneficiation process are crushing, grinding, gravity-based separation i.e., jigging (owing to the differences in specific gravity) and flotation (owing to the difference in the wettability). This may be followed by further refining process [28]. Among this, flotation separation method is the most popular technique.
