IJMMME Flotation of lithium ores to obtain high-grade

2020-1-20  Figure 7. Grade-recovery curve of the Gonçalo lepidolite froth flotation. Similarly to what occurred with spodumene, it was not possible to obtain concentrates with Li 2 O grades close to the Gonçalo lepidolite Li 2 O content (5.58 % Li 2 O [31]), even after the cleaning stage, having been 4.50 % Li 2 O the maximum value achieved. The shape of the grade-recovery curve indicates that the
