The main method used for lithium micas concentration is froth flotation using amine cationic collectors. However, challenges are raised to obtain good selectivity between lithium micas and other silicate gangue minerals, all these minerals having close surface properties and therefore floatability behaviours. ...

In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to the entrainment of gangue minerals. Industry has solved this challenge by introducing froth washing mechanisms. Clean wash water is introduced into or on top of the …

ABSTRACT Clay minerals are widely present in various ore deposits as gangue minerals. The processing of high-clay-content ores is becoming a significant challenge for the mining industry owing to the poor flotation performance caused by the presence of clay minerals. Different types of clay minerals are typically present in ore bodies, and they cause several …

The two higher tiers of flotation control are advanced flotation control (AFC) and optimising flotation control (OFC). AFC involves the rejection of the effects from input disturbances to the process (e.g. a change in feed grade) and maintaining performance parameters — grade and recovery (although care should be taken when defining recovery; in a dynamic situation …

Physicochemical Problems of Mineral Processing, 2018. This paper aims to provide a comprehensive review on the physico-chemical factors governing the flotation of Cu-Mo-Fe sulfide ores in seawater, which is different from NaCl or KCl solutions because it contains hydrolysable ions such as Mg 2+, Ca 2+, HCO3-, CO3 2-, etc., which can precipitate with lime as …
