Flotation of quartz particles assisted by nanobubbles

2015-4-10  Experimental studies of flotation of quartz particles, under various conditions and cells (setups), are presented. Pure and well-characterized quartz samples were treated with a commercial alkyl ether monoamine as flotation collector with bubbles in various sizes: coarse bubbles (400–800 μm); nanobubbles (200–720 nm); and their mixtures.The nanobubbles were generated by selective

Flotation of quartz from quartz-feldspar mixtures by the

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

Microbially induced flotation of alumina, silica/calcite

2011-5-8  Flotation behavior of haematite and quartz, calcite and corundum was studied before and after interaction with bacterial cell free extract and bacterial cells. From Table 3 it can be observed that percent flotation recovery of quartz was about 92% on interaction with bacterial cells and with bacterial cell free extract the recovery was about 90

Feldspar flotation as a quartz-purification method in

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 trace the stepwise enrichment of quartz to 95-100% purity with our procedure by X-ray diffraction analysis.

Selective Flotation of Quartz from Hematite by Amide

2021-7-30  The quartz recoveries at pH 10.5 with amide-amine were higher than those with etheramine in all the tested concentrations. At pH 10.5, the selective window in flotation of quartz from hematite was of 80%. The presence of secondary amide in the chemical formula of the reagent was identified through amide-amine infrared spectrum analysis.
