Froth flotation is considered as the most widely used effective process in environmental engineering for mineral separation [1], wastewater treatment [2], removal hydrocarbon from refinery waters [3], and oil saturated beach sands [4]. Its efficiency comes from the selective ability of separating hydrophobic from hydrophilic materials ([5], [6]).

In short, the single-mineral flotation results show PA-Na has a more preferential flotation separation of scheelite from fluorite than Na 2 SiO 3 at pulp pH between 8.7 and 10. The flotation recovery of scheelite and fluorite with 75 mg/L of 731 at the pulp pH 9.3~9.6 as the PA-Na concentration increased is shown in Figure 5 .

Fig. 3 shows the effect of water glass on the flotation performance of scheelite and calcite as a function of (a) water glass dosage and (b) solution pH value. As shown in Fig. 3 (a), when the dosage of water glass is less than 300 mg/L, the flotation recovery of scheelite decreases slightly, illustrating that scheelite is less sensitive to …

Froth flotation of scheelite – A review
The ideal pH for scheelite flotation however ranges from 8 to 11 with some authors restricting it between 9 and 10 [32], [33], [34]. A pH of 9 is usually given as the optimum regardless of the reagent combination. Different pH modifiers can be used in scheelite flotation, such as sodium hydroxide, sodium carbonate or calcium oxide.
