【摘要】 金厂沟梁金矿氰化原矿的工艺矿物学研究是在原矿金赋存状态研究基础上进行的．通过研究查清了氰化原矿的微量元素的特征、粒度的分布特征和氰化原矿的矿物成分．确定了金的赋存状态，进而对选治工艺进行了讨探，为提高金的选冶回收率提供了可靠的依据．更多还原

【Abstract】 The study on technological mineralogy of cyaniding sample in Jin changgouliang gold mine is based on the investigation about the occurence state of gold in the ores. The characteristics of microelements and main elernents, distribution of grain and mineral composition in cyaniding sample are found out.The occurence state of gold in cyaniding sample is determined and the process of mineral concentration is also discussed, which has provided a reliable information for improving the gold recovery.更多还原
