摘要

Method for recycling galvanized steel scrap comprises immersing the scrap in an alkaline solution, removing the zinc layer from the scrap in the solution to form an alkaline solution containing zinc ions, roasting or burning the zinc ore to form zinc oxide, dissolving the zinc oxide in sulfuric acid and combining the solution containing zinc ions with the sulfuric acid solution to precipitate zinc hydroxide.
