The effect of sodium silicate dosage
The effect of sodium silicate dosage on flotation performance of
phosphate was evaluated and the results are given in Figs. 3 and 4.
Phosphate recovery was increased as sodium silicate dosage
increased, reaching its maximum value at about 2 kg/ToF. At the
same time separation efficiency (SE) as defined in Eq. (1) did not
change with increasing sodium silicate dosage until a certain limit
(>3 kg/ToF). On the other hand concentrate grade (%P2O5) was not
