Abstract: Taking the recovery and refining of metallic copper in waste printed circuit board as an example,the basic experimental technologies such as material separation,electrolytic purification and determination of metal element content are organically combined to design a comprehensive experimental project.Students are familiar with the separation and sorting techniques.Students can grasp the principle of suspension electrolysis technology,consolidate the titration analysis operation,understand the process of recycling metal copper from waste circuit boards.Thus training students in comprehensive experimental skills at the same time establish the concept of recycling of resources.
