哥伦比亚金银赋存状态研究

哥伦比亚金银赋存状态研究

(Summary description)工艺矿物学发现的问题  对哥伦比亚V、H、Y三个子矿段样品进行金矿物粒度分析、金物相分析及金的配分计算,得出:  (1)V矿样中裸露金占73.6%,这部分金通过浸出可回收,硫化物包裹金占总金的27.74%,包裹可见金的粒度在0.05-30μm之间,这部分金通过浸出难回收,但可通过浮选回收;  (2)Y矿样中裸露金占97.05%,硫化物包裹金占2.5%,包裹金粒度较细,在0-20μm间,细磨对提高浸

  工艺矿物学发现的问题:

  对哥伦比亚V、H、Y三个子矿段样品进行金矿物粒度分析、金物相分析及金的配分计算,得出:

  (1)V矿样中裸露金占73.6%,这部分金通过浸出可回收,硫化物包裹金占总金的27.74%,包裹可见金的粒度在0.05-30μm之间,这部分金通过浸出难回收,但可通过浮选回收;

  (2)Y矿样中裸露金占97.05%,硫化物包裹金占2.5%,包裹金粒度较细,在0-20μm间,细磨对提高浸出率效果不明显;

  (3)H矿样中裸露金总量99.5%,硫化物包裹金占总金的0.13%,包裹的可见金粒度在0-10μm之间

  通过问题提出的建议:

  哥伦比亚V、H、Y三个子矿段样品大部分金矿物为裸露金,易于选冶回收,可回收价值大

  取得的效益:

  工艺矿物学结果查明哥伦比亚样品中金的配分及金矿物的粒度、解离-连生情况,结果为选冶实验提供可靠依据,为矿山建设提供参考。
