山东某难选金矿工艺矿物学研究

Study on Technological Mineralogy of a Refractory Gold Mine in Shandong Province

山东某大型难选金矿,品位较高,回收率低,资源浪费严重。本文从工艺矿物学的角度,查明矿石种类、主要矿物组成及嵌布特等,尤其对金矿物的种类、成色、粒度、形态及在矿石中的嵌存关系等工艺特征进行了详细研究,为选矿工艺流程的确定提供必要的工艺参数,为合理开发、利用该矿资源提供技术依据。

A large refractory gold mine in Shandong Province has high grade,low recovery and serious waste of resources.From the point of view of process mineralogy,this paper finds out the types of ore,main mineral compositions and intercalation of gold minerals,especially the types,colouring,particle size,morphology of gold minerals and their intercalation relationship in ores.It provides necessary technological parameters for the determination of beneficiation process flow,and for the rational development and benefit.The technical basis is provided by using the mineral resources.
