Feldspar flotation as a quartz-purification method in

We present a new froth flotation mineral-separation device and procedure that allows for very effective quartz enrichment before CN chemistry. Our flotation cell, which has a volume of 600 cm 3,is built of borosilicate glass, holds up to 90 g of sample, and achieves quartz and feldspar separation in ≤2 h for very feldspar-rich samples.

Flotation of quartz from quartz-feldspar mixtures by the

01-11-2016  Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939).

Flotation of quartz from quartz-feldspar mixtures by the

Quartz can be floated from feldspar in diluted HF solutions simply by the aid of frothers. • There is a high flotation separation selectivity between quartz and different types of feldspar. • A feldspar concentrate of 99.9% at a recovery of >95% was produced. • The results could be important for cleaning and recycling purposes.
