Abstract
Laboratory tests of relationship between kinetics of flotation of pure galena smaller than 38 µm in size and concentration of potassium butyl xanthate show that flotation rate undergoes considerable reduction when mineral grains are under 18 µm in size. Size grades below 18 µm show the slowest flotation rates that are nearly equal at the collector concentration of 0.5 mg/l. With the higher collector concentration, the flotation rate grows in all size grades under testing.
