    2011-11-1 · Preliminary flotation tests were used to process the phosphate samples. Results of preliminary flotation tests showed that they don t contain any desirable efficiency (grade or recovery) of P 2 O 5. Calcination was the best process for preconcentration of this ore. In the desliming stage about 14.4 of total P 2 O 5 was removed.
