“…While colored minerals typically oxides are floatable by anionic reagents, silicate minerals, particularly feldspars, are floated by cationic reagents [11,12,[37][38][39]. G-TAP which is used as cationic collector in this study is reported to be used efficiently in the flotation of feldspar minerals [40].…”

“…To this end, feldspars are mostly beneficiated by means of magnetic separation, flotation or combination of both methods [5,10,11]. However, the fines are disposed because they cannot be efficiently beneficiated by magnetic separation and they adversely affect flotation recoveries in the form of slime coating [11][12][13][14]. Flotation is the most popular method for removing these impurities in the size range of −250 to +38 m.…”

“…Slimes are usually discarded before flotation as they adversely affect flotation by covering valuable mineral surfaces through attractive forces [12,[15][16][17]. Recovery of these minerals from slime which includes a significant amount of valuable minerals will provide economic and environmental gains.…”

“…The mineralogical composition of feldspar minerals can be expressed in terms of the ternary system: albite is sodium rich feldspar, having an empirical formula of NaAlSi3O8, orthoclase and anorthite are potassium and calcium rich feldspar which are having an empirical formula KAlSi3O8 and CaAl2Si2O8 respectively. Chemically, feldspar is a group of aluminosilicate minerals containing sodium, iron, titanium, potassium, calcium, magnesium or the combination of these elements [3,4].…”

“…magnetic separation and flotation [5,6]. Several studies were conducted to improve feldspar's specifications to meet the requirement of ceramic industries [1,3,[8][9][10][11]. It is suggested that the specifications of feldspar in ceramic and glass industries are < 70% SiO2, > 17% Al2O3, < 0.1% Fe2O3, with > 5% of both K2O and Na2O [7].…”

Abstract. 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, is found about 20% of the total ore feed. Since 1985, company has been producing slime waste approximately 200,000 tons, causing a huge pile of stock and obstructing the operation area. The mineral compositions of slime waste by X-Ray Diffraction (XRD) showed that it consisted of albite, orthoclase, quartz, and ferrous impurity minerals such as muscovite, biotite, mica, and garnet. The elemental analysis by X-Ray Fluorescent (XRF) showed that the percentage of grade contained 72.53% SiO2, 15.70% Al2O3, 1.56% Fe2O3, 0.16% TiO2, 0.40% CaO, 0.07% MgO, 4.87% K2O and 4.38% Na2O. After that, this slime waste was sent to the processes of dirt washing, classifying, attrition scrubbing, separating the ferrous impurity minerals, and preparing for flotation by washing drum, trommel, attrition scrubber, cone classifier, permanent drum magnetic separator, wet high intensity magnetic separator, and hydrocyclone. At this stage, the slime mainly consisted of albite, orthoclase, and quartz with 74.43% SiO2, 15.15% Al2O3, 0.12% Fe2O3, 0.04% TiO2, 0.43% CaO, 0.01% MgO, 4.73% K2O and 4.75% Na2O at a yield 35%. Study on fine feldspar flotation, which is for removing quartz from feldspar, showed that the optimum condition of 20% solids must be adjusted to pH 2 by hydrofluoric acid (HF), using A-TD as a collector at 1,400 grams per ton feed, conditioning time and flotation time of 5 minutes each. The results of the study showed that the recovery of feldspar attained 69.7% with 67.82% SiO2, 18.54% Al2O3, 0.14% Fe2O3, 0.03% TiO2, 0.52% CaO, 0.006% MgO, 6.88% K2O and 6.07% Na2O, which meet ceramic industry's specifications.
