The selection and use of flotation reagents is the key to obtaining good flotation results. Studying the mechanism of action between reagents and minerals can not only explain the flotation phenomenon from a theoretical perspective, but also guide the selection and synthesis of reagents, and have a positive impact on the flotation process. Optimization goes a long way. Currently, the commonly used chemicals in mica flotation are collectors and inhibitors.

Collectors for mica flotation

Under different slurry pH values, the collectors used in mica flotation are also different. Under acidic conditions, cationic collectors are effective agents, such as long carbon chain amine acetate. Commonly used ones include dodecylamine and cocoamine. Under alkaline conditions, it is necessary to use a combination of anion and cation collectors. Long carbon chain amine acetate cation collectors and fatty acid anion collectors can be used in combination.

Mica flotation inhibitors

Mica mineral inhibitors are mainly used in certain situations where mica is used as gangue, and can be divided into gangue mineral inhibitorsandMica Mineral Inhibitors. At present, there are many studies on inhibitors of gangue minerals. In the acidic cation collector flotation process, sulfuric acid can not only control the pH value but also suppress quartz.

Starch has varying degrees of inhibitory effects on all silicate minerals. Under acidic conditions, starch can Quartz has the strongest inhibitory effect, followed by the inhibitory effect on feldspar minerals in the shelf-like structure, and the inhibitory effect on layered structure and double-chain structure minerals is very poor. Therefore, starch can also be used as an inhibitor of gangue minerals during flotation of sericite. In the alkaline anion and cation collector flotation process, sodium carbonate and calcium lignosulfonate are commonly used to suppress gangue. Water glass is a very widely used siliceous gangue inhibitor and is also used in mica flotation.

The above are the commonly used beneficiation reagents in mica flotation. In actual beneficiation, how to choose reagents should be based on the mica beneficiation requirements to determine the appropriate reagents and the appropriate dosage. Therefore, the editor recommends conducting mineral processing test analysis first, and then designing a suitable Mica flotation processand chemicals.
