The flotation rates of quartz, sphalerite, galena, and the samples of copper ores which were examined, follow a first order rate equation of the type: - d(C-Cco) _ K(C-Coo) where Coo is the concentration of the mineral in the flotation cell, even after a long flotation time. The flotation rate equation is used to predict flotation recovery, grade of concentrate, and separation efficiency as functions of flotation time. The predicted values of these quantities are in agreement with the experimental values. Laboratory procedures based on flotation kinetics provide more information than is usually obtained from the conventional laboratory flotation tests
