| Abstract: | The paper introduces results of a comprehensive investigation on copper mines all over China.Statistical data concerning mining recovery , processing recovery , comprehensive recovery were analyzed.Copper occurs mainly as sulphide , total output of ores was about 121059.6 kt. Large scale copper mines were accounting for 7 .60%in all in China and production capacity was accounting for 77.69%.Ming recovery was 92.45%, processing recovery 89.10%, comprehen-sive recovery 62 .70%.0 .49%waste rock , also 9 .18%tailings from mineral processing is reuti-lized. |
