摘 要: 从节约资源、减少能耗和改善环境方面说明我国开展金属二次资源循环利用的迫切性及面临的问题。我国在有色金属资源循环利用方面虽然取得了很大的进展，但总体的资源综合利用程度却依旧相当低下。炼钢锌灰、失效电池、废旧家电、印刷线路板、铜冶炼渣和电镀污泥的循环利用是很值得关注的金属二次资源循环利用领域。

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
