Increasing demand for lithium-ion batteries has led to the development of several new lithium mineral projects around the globe. Some major mineral processing challenges these projects face are similarities in gangue and value mineral behaviour and poor selectivity in froth flotation. Unsaturated anionic fatty acids are the primary …
This indicates that mica mineral particle sizes >380 μm are inappropriate for flotation separation (i.e., they precipitate regardless of the injected amount of collector). Therefore, it is necessary to mill the target soil to <380 μm particle sizes to remove F derived from mica minerals using the flotation separation technique.

In the case of pure mineral flotation, Bhappu and Fuerstenau (1964) ... In conclusion, mica flotation occurred, as expected. Nevertheless, the separation of feldspar and quartz must be improved. The results indicate that it is possible to separate micas from lepidolite flotation tailings and then, in the second phase, produce both a feldspar ...
Single mineral micro-flotation results show that coarse particles are beneficial for spodumene flotation separation. The previous experiments also indicate impurities such as mica can be separated at a coarser grain size.
Mica minerals are generally floated using long chain aliphatic amines (12–18 °C) at pH 2.5 ... which contains high level of titanium and iron oxide minerals and small amount of mica minerals. Single-stage flotation with fatty acid based collector in an alkali medium can be effectively used to remove main colored impurities together from the ...
A novel approach for flotation recovery of spodumene, mica and feldspar from a lithium pegmatite ore - ScienceDirect. Abstract. Introduction. Section snippets. …
lectively reject gangue minerals like micas, feldspars, and Fe-Al silicates, but their appli-cation can be particularly challenging in spodumene flotation as this requires the selective depression of certain silicate minerals, but not spodumene [20. 23]. With specifications of < 1.0% Fe 2O 3 for battery-grade spodumene concentrates and < 0.17% ...
1. Introduction. As an important technical measure, flotation is comprehensively applied in the separation of minerals from ores, waste water treatment and other fields; some researches have shown that even nematodes can be obtained from soil by flotation (Jenkins, 1964).According to different surface physical and chemical …
Micas account for a great number of lithium bearing minerals with lepidolite, zinnwaldite and lithian muscovite. These minerals are known as lithium micas. If the …
In t he feldspathic mineral flotation, mica minerals are removed with amine . type c ollectors at acidic p H: 3-3.5, then sulphon ate and oleic acid collectors a re used in order to separate .
Moreover, our recent flotation study has shown a considerably increased collection of gangue minerals, including mica and quartz, in the presence of graphite particles. We confirmed such …
The flotation separation of muscovite from quartz was investigated using mixed sodium oleate/dodecylamine acetate (NaOL/DDA) collectors. The experiments were conducted on single minerals and on a mixture of minerals, and their collecting performances were studied by means of Fourier transform infrared (FTIR) spectroscopy, …
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 flotation ...
