In the paper.we carried on a brief analysis for the(high)copper—gold concentrate.According to calculating theoretically the coordination number of copper cyanide complexes,we can obtain the variety trend of coordination in the different cyanide density.In copper cyanide solution,from the rule of the leaching rate of copper and the situation of it’S coordination,we can calculate the consumption of sodium cyanide in the process of copper—leaching.It is of great value to control the craft process with cyanidation—leaching from a copper—containing gold concentrate.

Key words: Gold concentrate, Cyanide, Coordination number of copper cyanide
