Flotation of quartz from quartz-feldspar mixtures by

2016-11-1  1. Introduction. 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).TON (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta

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. We

1. A froth flotation process for separating feldspar from quartz-feldspar sands ore consisting essentially of the steps of subdividing said ore to produce at least a fraction having a particle size less than about 1 mm, collecting said fraction and washing the same with water to effect des, introducing the washed fraction at a solid concentration of about 20-30 wt percent into an aqueous

2007-9-18  Froth Flotation. After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic. By adding a carbonated solution to the sample, we can separate up to 95% of the feldspar.

Separation of feldspar from quartz: Mechanism of

Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse reflectance FTIR studies. The reagent schemes are tested in bench-scale flotation for the separation of albite from Greek Stefania feldspar ore. The single mineral flotation tests showed the feasibility of

The froth flotation procedure is repeated until most of the feldspar fraction has been removed or no additional separation of quartz and feldspar is accomplished. For a granitic sample of ca. 400 to 500 g, we find that five to six rounds of froth flotation are needed before either the froth flotation process is complete and the vast majority of
