内蒙查干银矿床氧化带中银的赋存状态研究

A study on occurrence of silver in oxidized zone of the Chagan silver deposit, Inner Mongolia

通过对样品的化学全分析,矿物相分析,X射线衍射分析,研究了银与铁、镁、锰、铅的相关性,以及镜下观察,确定了查干银矿床氧化带中银主要以硫化银及卤化银等独立矿物赋存于褐铁矿中,颗粒微细。

In order to research the occurrence of silver in the oxidized zones in the Chagan silver deposit, we carried out a series of experiments, such as bulk analysis, mineral phase analysis, X-ray diffraction analysis, making a correlation analysis between silver and iron, magnesium, manganese, lead. Through the search of main minerals under magnifying glass, it is definite that the silver (mainly fine-grained argentite and iodobromite) in oxidized zone in Chagan silver deposit exists in limonite.
