 · The results of batch flotation, ICP-OES and XRD analyses show that the first flotation product is almost quartz, while more feldspar and little quartz exist in the sink product when compared with the FQA feed. The mechanism of PEA acting as the collector for the separation of quartz/feldspar has been investigated.

Difference Between Quartz and Feldspar | Difference Between

Quartz and feldspar are minerals that are found on the earth’s crust. Let us discuss some of the differences between quartz and feldspar. When comparing the two, feldspar is more commonly found than quartz. Quartz is a mineral that consists of silicon and oxygen. Feldspar is the name given to a ...

Selective flotation of K-feldspar from Na-feldspar in ...

The K-feldspar flotation was performed in alkaline environment (pH 10.5–11.6) with only the addition of NaOH as a modifier and non-ionic Brij58 as a frother, on a fluorine-amine activated bulk feldspar concentrate from the preceding feldspar-quartz separation. The K-feldspar flotation resulted in a K-feldspar concentrate of 14.3% K 2 O at 77% ...
