ore concentrate upgrading process

Upgrading Phosphate Ores with Rotary Kilns

And as high-grade ore deposits diminish, it becomes necessary to find economic ways to process and concentrate lower-grade sources of phosphate ores, effectively upgrading them into high-grade phosphate products. However, depending on the makeup and grade of the unique ore source, some ores are more difficult to process.

IJMMME Flotation of lithium ores to obtain high-grade

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
