A New Processing Technology of Comprehensive Utilization on the Gold Copper Ore

Abstract:

The character of one refractory gold copper mine located in the west of the Sichuan province is so complex, that the valuable element of the ore cannot be recovered by the traditional beneficiation processing. In this paper, a series of tests were conducted to optimize the suitable collector and develop a new beneficiation processing to recover the valuable associated minerals as while as the copper minerals. The results of the tests showed that the bulk-concentrate with 14.73% of Cu grade, 40.59×10^-6 of Au grade and 2360.00×10^-6 of Ag grade can be obtained from the recommended bulk flotation processing. The recommended processing showed in this paper could greatly improve the copper mineral recovery and reduce emissions of copper tailings, which is very important for the copper beneficiation technology development and the protection of the environment.
