Improved Quartz Flotation at Low Temperature by Amino …
A new type of amino acid surfactant, lauroyl lysine (LL), is used as a green collector for the low-temperature flotation of quartz. The micro-flotation test results indicate that, under flotation conditions of 10–40 °C, pH = 11.0, 20 mg/L CaCl2, and 60 mg/L LL, the highest recovery of quartz by LL could reach up to 97.08%. The temperature at which flotation occurs …

New directions in flotation machine design
To use the Smoluchowski equation, we need an estimate of the number concentration N b of bubbles in the flotation cell, which is related to the gas holdup. Dahlke and Gomez (2005) showed that in a flotation machine operating in a typical range of the superficial gas velocity J g, the gas holdup e was directly proportional to J g.
