The effect of NaOT/DDA ratio on the mica flotation was examined at pH 10.30 and a collector dosage of 180 g/t (Fig. 6 b). The results showed that the NaOT/DDA ratio had a great influence on the mica flotation. When using DDA alone, the mica products yield was the highest, but the grade of Fe 2 O 3 was low. This result indicated that feldspar ...

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 …

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.

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 ...

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.
