铁帽中次显微金的研究

Study of submicrogold in gossan

本文采用透射电子显微镜和电渗析的方法,研究了铁帽中次显微金的赋存状态、粒度分布及形态特征等,介绍了铁帽金透射电镜样品的研制和电渗析试验条件的选择,揭示了铁帽金的形成机理.

By using transmission electron microscopy and electrodialysis, this paper has studied the mode of occurrence, the grain size distribution and the morphological features of submicrogold in gossan.The preparation of TEM, sample of gossan and the selection of electrodialysis experiment condition are also introduced simultaneously, This paper reveals the formation mechanism of gold in gossan.
