A sample from the small-sized tailing pile of an Iranian mica processing plant was subjected to a series of mica recovery experiments. Mineralogical and microscopic investigations indicated that the dominant mica mineral was phlogopite which was accompanied by plagioclase feldspars.
In Fig. 3 is shown how extraction of mica into the concentrate (curve 1) and content of mica in the concentrate (curve 2) and of tailings (curve 3) vary with ANP consumption when the proportion of the compound II is optimum. The yield of railings in this case remain practically unchanged.

Keywords: flotation, gravity separators, mica flakes, reclamation, tailing disposal. 1. Introduction Mica minerals are common layer silicates that present in soils, sediments, and a lot of ore deposits and metamorphic rocks. They are crystallized in a monoclinic system with a pseudo-hexagonal tendency, and are similar in chemical composition [1-3].
A sample from the small-sized tailing pile of an Iranian mica processing plant was subjected to a series of mica recovery experiments.
The flotation experiment on tailings showed a recovery of Cd, Ga and Zn at pH 7 of 33%, 6% and 29% respectively. The present investigation highlights the methodologies used for extracting raw...
To increase the recovery of PGMs by the flotation process, a comprehensive understanding of gangue and valuable minerals is essential for optimising the extraction and processing of metals. ... The tailing sample also contained substantial quantities of naturally floatable gangue such as talc, clay, mica, and altered orthopyroxene, followed by ...

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 …
Results proved that shaking table could produce a mica concentrate with grade of 74%. Also, according to the flotation tests, it seemed the best size fraction was -150+75, and after that, …
The Minerals Research Laboratory is a world leader in research, development, and implementation of mineral processing techniques. The MRL is part of the North Carolina State University College of Engineering, under the …
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.

A sample from the small-sized tailing pile of an Iranian mica processing plant was subjected to a series of mica recovery experiments.
Results proved that shaking table could produce a mica concentrate with grade of 74%. Also, according to the flotation tests, it seemed the best size fraction was -150+75, and after that, -100+150. Flotation in combination with attrition scrubbing produced a concentrate with 92% mica content and 70% recovery.
The mica flotation concentrate and the 20-mesh trommel oversize, when combined, accounted for a recovery of about 77.5 percent of the mica present in the feed in a product containing 98.1 percent mica. ... A rougher froth was recovered and cleaned twice to produce a finished mica concentrate. The rougher tailing contained considerable coarse ...
The invention discloses a floating magnetic combined ore dressing process for recovering mica from iron ore mill tailings, which relates to the technical field of tailings recovering processes. The floating magnetic combined ore dressing process comprises the following steps of: firstly preparing iron ore mill tailings into ore pulp, and feeding into a whirlcone for desliming; feeding …

The tailing from the mica flotation cells at approximately 25% solids is conditioned about 5 minutes with 1 to 3 lbs. hydrofluoric acid per ton of solids. pH is kept in the range of 2.0 to 2.5. In some cases it is necessary to thicken ahead of the hydrofluoric acid conditioning step. This can be done by the cyclone arrangement as shown in the ...
Stage flotation of de-slimed ground ore is advisable. Mica impurity is first floated with a combination of fuel oil and some amine acetate in a pulp made acid with H2SO4. Second-stage flotation may be preceded by washing and re-conditioning with one of the petroleum sulphonates in a pulp made acid with sulphuric acid to remove additional iron.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or …
