The paper studies the kinetic of catodic of electrochemical recovery of copper from waste waters using copper powders cathode with granullarity in range -0.2+0.125 cm. The kinetic has been settled by comparing the experimental polarisation curves with those calculated using specific equations. The shapes of experimental curves require chosen an empirical equation to describe the kinetic process. Accuratecy of equation is proved by Student Function of errors.
