Abstract:Electrodeposition was adopted to recycle gold from the solution in the electrolytic tank. The effects of various factors were investigated respectively, including the current density, velocity, pH andNa2SO3 additive. The current density was the main factor affecting the deposition rate in that the greater current density would lead to sooner deposition rate, while velocity and pH value of the deposition rate exerted less influence; Na2SO3 additive was an important factor in that adding 2 g/L of Na2SO3 to the solution will result in the improved efficiency of electrodeposition.
