| Abstract: | This paper briefly introduces how to distingwishgold by the naked eye, puts forword a method to reduce or even remove the influence brought about by the factors such as buoyance, compressibility and surface tension when a liquid draining weight less method is used in the determination of the relative purity of gold, and works out an accurate, rapid and no gold lossing determination method with criterion gold standardized. |
