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). (1979) reported that HF creates a large difference in the …

A commercial feldspar product usually contains more than one feldspar mineral, and flotation conditions for the separation of individual feldspar minerals have been developed to produce individual feldspar minerals for specific applications. Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an …

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 …

Flotation separation at pH 8–9 is found to be feasible for the efficient separation of spodumene from feldspar using the mixed BHA/DDA collector (at a molar ratio of 6:1). In this system, DDA first forms a complex with BHA through hydrogen bonding, which then adsorbs onto the mineral surfaces.

Potassium feldspar, often referred to as K-feldspar, is a commonly occurring mineral found in many types of rocks, particularly in igneous and metamorphic rocks. It is an essential raw material in ...

Abstract. This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves. Much of the published information on feldspar ...

The sample of quartz sand stone was taken from the plant "Feldspar" Bujanovac at the beginning of the milling operation. The size range −0.6 to +0.063 mm was used for further investigations. ... Hydrofluoric acid (HF), which is the main regulator used in the flotation of feldspar, may cause serious environmental and health-related ...

In many mineral processing plants, using saline water has become necessary to improve water efficiency. However, the dissolved ions in the water such as Ca 2+ and Mg 2+ may have a significant negative impact on the flotation of RE (rare earth) minerals due to the chemical reaction with flotation reagents used in RE flotation. Although some …

For the sink products, the feldspar content of 4-S-Fsp reaches 94.77% and the SiO 2 grade is 69.50% at a feldspar flotation recovery of 87.45%. A competitive-adsorption model is proposed to explain the mechanism of the direct float of the quartz from the quartz-feldspar mixed minerals under neutral pH conditions.

The sample of quartz sand stone was taken from the plant "Feldspar" Bujanovac at the beginning of the milling operation. The size range −0.6 to +0.063 mm was used for further investigations. ... For flotation of feldspar better recoveries were obtained with the application of the collector Aero 3030C (19.58%) than with collector Flotigam ...

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 ...

These results indicate that a moderate amount of SA can effectively depress feldspar and has a minimal effect on the adsorption of DDA on the surfaces of spodumene. Therefore, the optimum reagent scheme for the flotation separation of spodumene from feldspar in the subsequent flotation tests was SA (30 mg/L) + DDA (0.2 mM).

The micro-flotation tests were carried out in flotation machine of XFG-1600 with a 40 ml hitch groove flotation cell. The impeller speed was fixed at 1700 rpm.

The color variations in moonstone are often due to the presence of different types of feldspar within the stone. What really sets moonstone apart is its phenomenon called adularescence – a soft, glowing light that seems to move across the stone's surface. This glow, combined with its often translucent quality, gives moonstone a dreamy ...
