由总公司科技协作网办公室主持召开的全国再生金属技术交流会于1986年5月14日在广州举行。历时4天的会议,紧凑热烈。会议文集含论文42篇,有25篇在大会上宣读。来自全国60多个单位近百名代表就再生金属的回收利用、国内外技术发展动态以及有关方针政策进行了认真而全面的讨论。一致认为,再生金属生产的原料品位高,容易处理,生产费用、能源消耗和建设投资均较处理原生矿低得多,对于有色金属的生产发展具有重要意义。但是,当前还存在许多不利发展亟待解决的问题。如条块分割,原料和产量不清,缺乏宏观 The National Seminar on Recycled Metal Technology, chaired by the Office of Scientific and Technological Cooperation of the Corporation, was held on May 14, 1986 in Guangzhou. The four-day meeting is very compact and intense. The proceedings of the conference included 42 papers and 25 papers were read out at the conference. Nearly 100 delegates from more than 60 units nationwide held a serious and comprehensive discussion on recycling and utilization of recycled metals, domestic and international technological developments and relevant guidelines and policies. They all agreed that raw materials produced from recycled metals are of high quality and easy to handle. Production costs, energy consumption and investment in construction are much lower than that of primary mines, which is of great significance to the production and development of non-ferrous metals. However, there are still many problems to be solved urgently. Such as segmentation, raw materials and output is unclear, the lack of macro
