Gold curtain factory in Hong Cui gold factory gold run metallurgy point 1978 began gold metallurgy production, the election gold number from 6 to 113. In the past three years, 5119 tons of gold-bearing ore was implemented 8 times a small cash collection work , Accumulative total production of 70.82 kg of pure gold, the cumulative election Metallurgical real yield was 86.56%, net profit of 350,000 yuan as much as possible, and achieved good technical and economic results.In order to give full play to the gold mining production potential, analysis and study of mining The characteristics of the process to improve the selectivity recovery rate, will have universal and practical significance, this paper some methods and production practices of the plant indigenous gold, the analysis is summarized as follows:
