Then some models have been developed with an objective of forecasting entrainment in a flotation cell, because this process plays a crucial role on the grade decision in the concentrate [86], [121]. In graphite ore, sericite is one of the main gangue minerals, and thus it is a major impurity in graphite flotation concentrate [128].

From 0.10 to 0.25 g, the graphite flotation recovery was decreased. From 0.25 to 0.50 g (Fig. 7 b), the graphite flotation recovery also decreased. When the β-cd weight was increased from 0.50 to 1.50 g, the graphite flotation recovery was similar to the high ash content part and reduced in comparison to the low ash content part.
