Abstract. 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.
Froth flotation 2. This document discusses reagents used in froth flotation processes. It describes how collectors like xanthates selectively attach to surfaces, making them hydrophobic. Frothers like MIBC and polypropylene glycols stabilize bubbles to form persistent froth. Collectors work best at optimal dosages, as too little reduces ...

So far, the froth flotation technique is the most commonly applied physicochemical separation approach to the mining industry, which processes annually more than two billion tons of primary and secondary resources.
This review has classified and analysed froth flotation models for control purposes. Only flotation pulp phase models are currently suitable for control. Gaps in knowledge on froth phase models for control purposes are analysed. Further model development is crucial for effective flotation model-based controllers.
Froth flotation is widely regarded as one of the most efficient and economical methods for separating ultrafine particles. Froth flotation is a chemico-physical separation process commonly used to separate constituents based on differences in surface wettability. Since nearly all minerals exhibit some distinction in surface characteristics, froth flotation can, …

There is still no appropriate technology that can optimize bubble size distribution, production rate and cost together for industrial froth flotation application.
Sometimes, flotation is used as a subsequent and/or complementary stage in an effort to achieve a cleaner product. For eclogite type of rutile ores, besides physical separation approaches, froth flotation is seen as an efficient technique applied for separating rutile from associated gangue minerals (Li et al., 2016 ).
Froth characteristics: Observe the behavior and characteristics of the froth during the flotation process. The froth should be stable, with good froth depth, consistency, and texture.
