Copper consumption increased very quickly in China in recent years,which could not be met by inland copper *** order to achieve a sustainable development of copper industry,an analysis of copper recycling in China was *** the life cycle of copper products a copper-flow diagram with time factor was worked out and the contemporary copper recycling in China was analyzed,from which the following data were *** average life cycle of copper products was 30 *** 1998 to 2002,the use ratio of copper scraps in copper production,the use ratio of copper scraps in copper manufacture,the materials self-support ratio in copper production,and the materials self-support ratio in copper manufacture were 26.50%,15.49%,48.05% and 59.41%,*** materials self-support ratios in copper production and manufacture declined year by year in recent years on the whole,and the latter dropped more *** average index of copper ore and copper scrap from 1998 to 2002 were 0.8475 t/t and 0.0736 t/t,respectively;and copper resource efficiency was 1.1855 t/*** efforts should be paid to reduce copper ores consumption and promote copper scraps *** scraps were mostly imported from foreign countries because of shortage in recent years in *** the reasons related to copper scraps deficiency were also *** we can forecast:when copper production was in a slow rise or in a steady state in China,the deficiency of copper scraps may be mitigated;when copper production was in a steady state for a very long time,copper scraps may become relatively *** to the status of copper industry in China,the raw materials of copper production and manufacture have to depend on oversea markets heavily in recent years,and at the same time,the copper scraps using proportion and efficiency in copper industry should be improved.
