| Abstract: |
| high copper content in the copper sulfide ore, in the light of these characteristics is proposed in this paper is suitable for the sample mixture ratio, high temperature melting, gold, silver and lead to the formation of alloy, using the proportion of the poor separation and slag, will lead button ash blowing gold, silver grains with nitric acid, the determination of gold in gold, determination of silver content with gravimetric method, volumetric method. Relative standard deviation of the method is 0.66% to 4.78%, the recovery rate of 96.5% to 100.6%. |
