FLOTATION SEPARATION OF FELDSPAR KATAYANAGI A,JA

If the amount of the flotation reagent is increased, the resulting feldspar has a reduced content of Al 2 O 3 and Fe 2 O 3, although the yield of feldspar itself is increased. Therefore, the amount of the flotation reagent should be selected depending upon desired quality of the recovered feldspar and the separation efficiency.

Understanding the flotation separation of Na and K

2018121Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Nafeldspar albite and Kfeldspar microcline minerals were investigated in the presence of K ion as counter ion. In order to identify the role of K ions on the selective separation of feldspar minerals, solubility, adsorption

202065Fig. 2 shows that the effect of pH on the flotation recovery of spodumene and feldspar using individual collector at dosage of 4 10 4 mol/L. When DS was used as a collector, the recovery of spodumene and feldspar at neutral pH range were high, reaching more than 60 . Moreover, it can be seen that the recovery of spodumene and feldspar were relatively close throughout the studied pH

Effects of metal ions on the flotation separation of

202171As shown in Table 5, it was easier for C 12 H 22 BrO 2, Ca 2, and Mg 2 to adsorb on spodumene than on feldspar and quartz therefore, CaII and MgII facilitated the flotation separation of spodumene from feldspar and quartz. However, the adsorption of FeIII and CuII on the three minerals was complex.

In situ adsorption of mixed collectors BHA/DDA in

20201115Flotation separation at pH 89 is found to be feasible for the efficient separation of spodumene from feldspar using the mixed BHA/DDA collector at a molar ratio of 6:1. In this system, DDA first forms a complex with BHA through hydrogen bonding, which then adsorbs onto the mineral surfaces.
