The entrainment behaviour of sericite in …
10-03-2014 · For the − 30 μm size fraction of microcrystalline graphite, the values of entrainment factor of sericite in artificial mixture flotation were 1.08 (graphite concentration: 5%), 1.21 (graphite concentration: 10%), 1.29 (graphite concentration: 20%), respectively, all of them were greater than one, this should be attributed to the entrapment of sericite in the froth phase.

A suitable grinding fineness and flow-sheet could potentially reduce the mechanical entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind size of this ore should be 92% passing 74 μm based on the ...
