在研究了用氨性硫代硫酸盐溶液浸取含铜硫化金矿的基础上,进一步探讨了浸取过程中矿物物相的变化。通过扫描电镜、x射线粉末衍射、差热分析等检测方法,结合浸取的实验结果,查明了河台硫化金矿中金的赋存状态。用氨性硫代硫酸盐溶液浸取含铜硫化金矿时,发现氨水对硫代硫酸盐的协同效应是提高金浸取率的根本原因。 On the basis of studying the leaching of copper-bearing sulfide gold by ammonium thiosulfate solution, the change of mineral phase during the leaching process was further studied. Through the scanning electron microscopy, X-ray powder diffraction, differential thermal analysis and other detection methods, combined with the experimental results of the leaching, ascertain the gold deposit in HeTai sulfide gold deposit. When ammoniated thiosulfate solution was used to leach copper sulphide-containing gold, the synergistic effect of ammonia on thiosulphate was found to be the fundamental reason for increasing gold leaching rate.
