It is often challenging to separate lithium minerals from their associated gangue minerals (e.g., quartz, feldspar, mica) due to their similar physical-chemical properties [2, 3]. The typical beneficiation mainly include flotation, hang sorting, heavy media separation, thermal treatment and magnetic separation [4].

Gravity separation can be used for mica–feldspar separation because mica generally takes the form of flaky shapes, which are pliable, resilient, and tough. Pinched sluice was used to remove flaky mica minerals from albite, and the effects of feed solid …
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 feldspar concentrate from the preceding feldspar-quartz separation. The K-feldspar flotation resulted in a K-feldspar concentrate of 14.3% K 2 O at 77% ...

Therefore, the flotation separation of spodumene from feldspar and quartz, may be achieved at a certain NaOH dosage. In order to examine the effect of NaOH on the flotation separation of spodumene from feldspar and quartz, the flotation of mixed minerals (spodumene:feldspar:quratz = 2:1:1, wt%) is carried out, and the results …
A comparison of the specific gravities of the major constituents of mica ores (muscovite 2.67+, quartz 2.65, kaolin 2.61, and feldspar 2.57) indicates that an effective separation of muscovite from the other minerals can be made in heavy liquids at a specific gravity as low as 2.68.
This work explored a clean flotation process for separating mica, quartz-feldspar from granite tailings. For mica flotation, sodium carbonate (Na 2 CO 3) was used as pH adjuster, and sodium oleate/octanol with mass ratio 9/1 (NaOT) and dodecylamine (DDA) were used as mixed collectors. Subsequently, quartz-feldspar separation was …
In this paper, a complete scheme aimed at improving the flotation performance of spodumene and comprehensively recycling mica and feldspar from lithium tailings in an economical and environmentally friendly way is put forward. The flotation performance of spodumene and feldspar with four size ranges (0–19, 19–38, 38–45 and …
Feldspar ( / ˈfɛl ( d) ˌspɑːr / FEL (D)-spar; sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. [3] The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium ...
The selectivity in flotation separation of spodumene from other pegmatic aluminosilicates such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult.
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 …
Single-mineral flotation results showed that using 30 mg/L SA allowed the separation of spodumene from feldspar at pH 6, although there was a strong pH dependence. Zeta potential measurements and FTIR analysis showed that SA and DDA can adsorb onto both minerals. ... mica and feldspar from a lithium pegmatite ore. …

The separation of spodumene from other minerals (such as feldspar, quartz, and mica) has always been a challenge on account of their similar surface characteristics [9], [10], [11]. Flotation is an effective technology for the enrichment of spodumene and feldspar.
Using sieving, carbonate-organic matter removal, water flotation, magnetic separation, heavy liquid separation, and HF solution etching, we separated quartz, feldspar (plagioclase), mica, and the heavy minerals and measured the ESR signal in each of them to examine the impact of impurities within mineral grains on the ESR signals.

Feldspar for ceramic/glass industries requires sufficiently low content of harmful colourants (Fe-, Ti-, Mn-bearing mineral phases). Hydrothermally altered albite-rich granites are increasingly used as feldspar raw material nowadays; however, they are often marked by increased content of colourants, which must be removed during the …
Weathered granite contains a high concentration of feldspar, quartz, and kaolin. However, while it becomes rich in clay due to strong physical weathering, the granite minerals that are not fully weathered are still very hard, which makes the grinding process more difficult and limits its use. This study proposes a multi-step process involving …
