Nov 01, 2016  Fig. 1 shows the results of single mineral and mixed binary minerals flotation tests. It can be seen from Fig. 1(a) that individual collector (DDA or NaOL) flotation shows some selectivity. However, the scheelite recovery is lower than 78%, and very sensitive to the SS dosage. Notice that mixed DDA/NaOL collectors show a much better selectivity.
