| 摘 要： | 通过对地壳、海洋及人体中16种元素丰度的分析，得出了环境友好型生产工艺的3个特征，即：整体偏碱性、氧硫比接近2000：1、避免使用低丰度元素。此外还结合上述特征对加压氧化-氰化法和次氯酸钠一步浸金工艺的环境友好性进行了分析。

| Abstract: | Abundance of 16 elements in earth＇s crust, oceans and humans are studied in this article. As a conclusion,3 features of environment - friendly process are summarized which are：alkaline substances domination, O/S ratio approaching to 2000： 1 and less consumption of low abundance elements. Compression oxidation - eyanidation process and one step leaching process with sodium hypochlorite in gold production are analyzed according to the features above. |
