In general, the extracted raw material is referred to as alkaline-feldspar granite, leucogranite, albitic granite or even feldspathite (alkali-feldspar syenite [37]). Feldspars make the major rock-forming mineral with reported predominance of albite (30–50%) over K-feldspar (20–30%); however, they can make over 75% in feldspathite varieties ...

The flotation performance of spodumene and feldspar with four size ranges (0–19, 19–38, 38–45 and 45–75 μm) are investigated in single mineral micro-flotation tests.

On the contrary, limited Al sites on feldspar leave more space for BHA co-absorption with DDA on the surface of minerals, though after the sorption of DDA first. Thus, the flotation recovery of feldspar is higher than that of spodumene (Fig. 5). Download : Download high-res image (875KB) Download : Download full-size image; Fig. 9.

In order to understand the mechanism of selective feldspar flotation, the amount of released Na + ions from microcline and albite minerals were measured in the presence of KCl, and the results are shown in Fig. 1.As seen from Fig. 1, the amount of Na + ions released from microcline and albite increased with increasing KCI concentration, …

The K-feldspar flotation was performed in alkaline environment (pH 10.5–11.6) with only the addition of NaOH as a modifier and non-ionic Brij58 as a frother, on a fluorine-amine activated bulk ...

The spodumene-feldspar flotation system has profuse Si 4+ and Al 3+ ions, which act as potential chelating sites for sodium alginate on the mineral surface. The presence of a higher proportion of Al 3+ and unsaturated O ions on the spodumene surface in comparison to feldspar facilitates the formation of a reticulated structure of DDA and …

Feldspar flotation is widely used to purify raw feldspar ores. Arkema has applied its expertise in industrial mineral flotation and feldspar processing to custom-develop flowsheet designs and flotation reagents based on customer-specific ores that efficiently recover higher-grade feldspar minerals for a variety of end-use applications. Our ...

The slime waste from feldspar flotation plant at Attanee International Co., Ltd. in Thailand, contains orthoclase, albite, quartz, and ferrous impurity minerals such as biotite, muscovite, mica ...

The tailings were then floated to remove the soda-feldspar and quartz by reverse flotation, and produce a spodumene concentrate grading 7.25% Li 2 O (Cerny et al., 1996). During spodumene flotation, mixtures of petroleum sulfonate and fatty acids (LR19) was used as collector, and Na 2 CO 3 was used as a pH modifier. The …

Feldspar STUDY OF FELDSPAR FLOTATION. September 1983 Authors: Nils-Johan Bolin Boliden Mineral AB Abstract The study included comparative …

Potassium, which is included in certain contents in the structure of K-feldspar minerals, has a very important function in the growth of plants. Turkey hosts the largest feldspar reserves in the world and is by far the leader in feldspar mining. The production of potassium salts from local natural sources can provide great contributions both socially …

The purpose of this research is to recover slime waste from feldspar flotation plant at Attanee International Co., Ltd., Tak province. Slime waste with particle size less than 230 mesh,

Nepheline syenite is an igneous rock primarily made up of nepheline (Na, K) AlSiO4, sodium feldspar (albite, NaAlSi3O8) and alkali feldspar (orthoclase, …

Keywords: feldspar, flotation, sodium chloride, selectivity, mechanism 1. Introduction Na-feldspar (albite) and K-feldspar (orthoclase or microcline) are different feldspar minerals with similar crystal structures and close chemical and physical properties, mostly found in the same ore matrix. The selective recovery of these minerals from ...

The flotation and adsorption of sodium oleate (NaOL) on spodumene with four different particle size fractions (45–75 μm, 38–45 μm, 19–38 μm and 0–19 μm) were investigated. The flotation recovery increases upon slightly decreasing the size fraction, reaching a peak value at a size fraction of 38–45 μm. The recovery then decreases ...

Feldspar minerals (KAlSi 3 O 8, NaAlSi 3 O 8, CaAl 2 Si 2 O 8) are the most abundant of aluminosilicate rock forming minerals, comprising 60% of the earth's crust.They are widely applied in the production of glass, ceramics, and as fillers and extenders [1,2] in the paper and paint industries.In order to improve the purity or the whiteness of feldspar, …

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 minerals ...
