Abstract: |
This paper mainly studies the analytical conditions such as dissolution, enrichment and separation,adsorption enrichment, and desorption of gold in lead concentrate, especially in high lead ore. The samples were pre-concentrated by polyurethane foam and determined using atomic absorption spectrometry. The results indicated that the relative standard deviation (RSD) was less than 5% and the accuracy could meet the production requirements. The method for the separation of gold by polyurethane foam pre-concentration was easy to operate and need no special devices. It had high selectivity, as well as accelerating analytical speed and reducing analytical cost on the basis of ensuring the quality of analytical results. |
