Abstract:The urgency and problems for recycling utilization of metal secondary resource in China are highlighted in terms of resource saving, energy reduction and environment promotion. Although great progress has been achieved for recycling utilization of nonferrous metal resource, the overall resource utilization is still in low level. Zinc ash in steel industry, spent batteries, worn electrical devices, printing circuitry boards, copper smelt residues and electroplating sludge are key issues in recycling utilization of metal secondary resource.
Key words: recycling of resource; zinc ash in steel industry; spent batteries; copper smelt residues; electroplating sludge
