Mica flotation can be carried out in acidic or alkaline pulp, and the cations of long carbon chain amine acetates and anions of fatty acids are mica collectors. The flotation method is mainly used in the recovery of crushed mica and fine-grained mica in the sand and gravel industry, especially the mica resources in the tailings .
In the first flotation stage, mica is removed with an amine collector. In the second stage, titanium and iron oxide minerals, such as ilmenite and magnetite, are removed using an anionic collector. In the third stage, feldspar is activated with fluoride ions and floated with an amine. The residual product is usually high grade quartz.

Both samples underwent several bulk processing stages to prepare the spodumene flotation feed, including stage crushing and grinding to a P 80 of 170 µm; wet high-intensity magnetic separation (WHIMS) at 10,000 Gauss; mica pre-flotation with an amine collector; high-intensity alkaline scrubbing with NaOH; and several desliming …
The adsorption of dodecylamine acetate (DAA), sodium oleate (NaOL) and DAA–NaOL mixtures on muscovite mica were investigated through flotation tests, zeta potential measurements, and pyrene fluorescence tests. The results show that the muscovite mica has a negative charge over the pH range 2–12. The muscovite mica did …
The first method is to flotation mica in acidic medium with amine collector, the pH value is controlled below 3.5, and the upper limit of the flotation particle size is 1.2mm. And desliming is required before flotation. When the slurry concentration is 30-45%, the concentrate recovery rate can reach more than 77%, and the concentrate …
