METHOD FOR LEACHING VALUABLE METALS CONTAINED IN COPPER REMOVAL SLIME

摘要

In the present invention, a method for leaching valuable metals contained in a copper removal slime is characterized in that during oxidative leaching with hydrochloric acid of valuable metals contained in a copper removal slime by adding hydrochloric acid and an oxidant to a slurry of the copper removal slime, the slurry is stirred, and slurry recirculation is carried out to extract slurry from the bottom of the tank and resupply the slurry into the tank from the top of the tank.
