本文报道了从硫精矿和各种焙烧矿物中提取金的研究工作。发现金的提取率随着浸出矿物中硫含量增加而降低,由于矿物的多孔性,特别是当金和其它导电矿物接触时,也随着金的阳极溶解的钝化作用而降低。这可用金的氧化电位曲线和溶解氧的还原电位曲线来解释。
This paper reports on the extraction of gold from pyrite concentrates and various roasted minerals. It was found that the extraction rate of gold decreases with increasing sulfur content in the leached mineral and decreases with the passivation of gold anodic dissolution due to the porosity of the mineral, especially when gold and other conductive minerals are in contact. This can be explained by the oxidation potential curve of gold and the reduction potential curve of dissolved oxygen.
