A method has been developed to measure the streaming current of gas bubbles in aqueous solutions of inorganic electrolytes and of dodecylamine hydrochloride. The streaming current data obtained in dodecylamine hydrochloride solutions has been compared with the zeta potential and the flotation recovery of quartz for the same solution conditions. The significance, in the flotation recovery of quartz, of the relative surface charges on the gas bubbles and on the quartz is discussed
