Longhua Xu separated spodumene from feldspar with a mixed collector NaOL/DTAC, and obtained a concentrate with Li 2 O grade of 5.57% and Li 2 O recovery of 71.13% in the flotation experiments of an artificially mixed ore (Xu et al., 2016).

Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was ...

present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture.

Feldspar recovery in the concentrate, being 86.67% without dewatering/washing increases to 94.58% after three stage dewatering/washing between mica and metal-oxides flotation stages.

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. The results show that the maximum spodumene recovery is obtained with coarse particles of 38–45 μm, while for feldspar, the best flotation performance is …

The recovery of quartz could in turn be calculated from the recovery of feldspar. The feldspar recovery in the flotation concentrate (ε F-K, %) was calculated using Equation (1). Thereby, the recovery of quartz in the flotation concentrate (ε Q-K, %) was calculated using Equation (2). The mineral samples were ground to below 5 μm with …

The feldspar concentrate was the floated product obtained from the flotation process. This concentrate was obtained under the optimum conditions to feed …

A concentrate of more than 99% feldspar was produced after the first flotation, while 94% quartz was produced after the third flotation. The total float …

The recovery of spodumene, feldspar and quartz under this condition was 5.39%, 89.31% and 91.7% respectively, which indicated that PPPDA had the potential to be used as a collector in reverse flotation of crude concentrate. The adsorption mechanism was investigated systematically by zeta potential, FT-IR, AFM, and adsorption amount …

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 ...

Spodumene is one of the important lithium resources, so it is of great significance to concentrate it. Beneficiation methods of spodumene include magnetic separation, gravity separation, and flotation. Since the major gangue minerals of spodumene are quartz and feldspar, flotation becomes the most important way to …

Acidic flotation: Under the action of pH=2-3, use an anion-cation mixed collector to preferentially float feldspar. #2. Neutral flotation: In the natural neutral medium, use an amine cationic collector to float feldspar. ... which can effectively improve the grade of feldspar concentrate. For feldspar ore with difficult beneficiation and fine ...

The recovery of spodumene and feldspar was 72% and 1% respectively, and a concentrate with Li 2 O grade of 4.6% and recovery of 88% was obtained in an artificial mixed ore flotation test [12]. Tianjia used a mixture of NaOL and DTAC as collector to separate spodumene from feldspar and explored the adsorption mechanism deeply [13].

The lithium pegmatite ore for batch flotation was also from the Jiajika Lithium Mine. The multi-elemental chemical analysis of the ore was conducted by acid dissolution and Atomic Absorption Spectroscopy (AAS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and the analysis results are shown in Table 2.As shown in …

These results indicated that HPS leaned towards complex formations with Al-sites on the surface of feldspar, thereby reducing the adsorption of NaOL and inhibiting …

1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while ...
