| Abstract: |
| The particle size of gold concentrate sample directly affects the precision and stability of the determination of gold content in gold concentrate. In this paper, samples of different particle size were obtained by using different grinding tools and with different length of grinding time for Golden Grove gold concentrate, gold content of different samples was tested, and the precision of the results was analyzed. Measurement precision of B sample is the best, the grind mothod is with drum grinding machine, sample grinding time of 5h and particle size of grinding sample of 0.040mm (360 mesh) above 95%. The precision of C sample determination is relatively poor, which indicates that the uniformity of the grinding sample is relatively poor. |
