2018-1-1  Our flotation cell is built of borosilicate glass, holds up to 90?g of sample, and achieves quartz and feldspar separation in =2?h. • The procedure uses air bubbles to which the feldspars attach, 0.2% HF to reduce the surface energy of quartz, dodecylamine solution as a feldspar collector, and operates at a pH range of 2.4–2.7 at room temperature.

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).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta ...

2015-11-5  Cationic flotation of feldspar (amine + HF) in presence of NaCl was conducted by CengizDemir of Turkey in 2010 to separate both Na- and K-feldspar [3]. NaCl addition controls amine adsorption on sodium feldspar through adsorption of Na+ ions onto the mineral surface [3]. The use of NaCl addition in flotation was found to increase the K-feldspar

2006-1-1  Flotation tests show that the amine concentration ought to be kept lower than 1.47 × 10 −5 mol/l (≈5 ppm) to prevent feldspar loss during metal-oxides flotation stage and hence dewatering/washing operation after mica flotation seems to be a crucial step. Feldspar recovery in the concentrate, being 86.67% without dewatering/washing ...

2020-8-31  The study also indicates that the use of anionic collector sulfonate alone has a negligible effect on the feldspar flotation due to non-adsorption of the collector on the mineral surface as is evident from the infrared spectra data. Sekulic et al. reported a comparative study of feldspar flotation using two commercial collectors, AERO 3030C ...

2017-6-8  Fig. 3 shows the flotation recovery of spodumene and feldspar as a function of pH in the single collector NaOL and DTAC. Fig. 3 shows that the best pH range for the flotation of spodumene using anionic collector NaOL is 8–9, as most studies have recorded (Xu et al., 2016b). Because the maximum flotation recovery of spodumene using NaOL is ...
