IJMMME - Flotation of lithium ores to obtain high-grade Li2O

Froth flotation tests were conducted in a Leeds open-top laboratory flotation machine with a 3.0 L cell, at an impeller speed of 1000 rpm and an air flow rate of 7.5 L/min. These reported tests were chosen among others, carried out to assess the feasibility of froth flotation to produce Li 2 O concentrates.

Froth Flotation Process - Detailed Explanation With

2020/04/06 · In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out.

terms of froth recovery. A column cell was used in all the tests, because columns can be run continuously, allowing a wider range of froth depths to be investigated and allowing for enhanced detection of froth effects. The first part of the experimental work was performed in the laboratory at UCT, using Merensky ore.
