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 actual production and application, the preliminary process flow should be determined according to the nature and characteristics of the actual ore.
Process flow of flotation mica In general, the technological process of flotation mica is determined according to the beneficiation method. Due to the different properties of mica ore, during flotation, it is necessary to go through multi-stage roughing, multi-stage selection and sweeping processes to obtain ideal mica. concentrate.

The flow diagram of the micro-flotation tests are demonstrated in Fig. 3. The flotation temperature was maintained at 25 °C. The mineral suspension was prepared by adding 2.0 g of minerals to 35 mL of distilled water. The slurry was agitated for 1 min before adjusting the pH. Then the collector with desired concentrations was added into …
After performing the froth-flotation separation on the collected mica mineral sample using the optimal pH condition (i.e., pH 3.5) with the same concentrations of the collector (Armac-T = 1000 mg/kg-soil), and the frother (AF65 = 50 mg/kg-soil) and the same flow rate (80 L/h) and injection time (5 min) of the compressed air, the particle size ...
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 …
Flotation of lithium micas and especially lepidolite is becoming a matter of increasing interest, as a result of the increased demand in lithium for the battery and other sectors of modern technology. Gangue minerals of lithium-mica deposits behave similarly during flotation, resulting in a difficult separation contrast.
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 …

Mica is an essential non-metallic mineral widely used in various fields such as electrical, electronics, and construction. This article will provide a detailed overview of the production process of mica, from the extraction of ore to the preparation of the finished product, helping you gain a comprehensive understanding of how mica is produced.
So what is the ore processing flow of granite-type feldspar ore beneficiation? You can know about the process flow well from the following. Generally, for this type of feldspar ore, the process flow of crushing - grinding - classification - flotation (removal of iron, mica) - flotation (quartz, feldspar separation) is often used.
Finally, with respect to the results of all implemented experiments, a processing flow sheet was proposed for mica reclamation from the mentioned waste disposal. Specifications of the flotation tests
