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.
