巴鲁巴铜钴矿床硫化矿物解离度特性探索

Research on the Degree of Dissociation of Sulfide Minerals at Baluba Cu-Co Deposit

通过采集矿石样品进行矿物鉴定,查明了巴鲁巴铜钴矿床的矿石矿物组成。在此基础上,在显微镜下用线段法对光片中硫化铜矿物、硫铜钴矿和黄铁矿的嵌布粒度,以及对这些矿物在不同磨矿细度下的单体解离度进行了测定和统计,得出了在相同磨矿细度条件下硫化铜矿物与硫铜钴矿、黄铁矿的单体解离度差异较大。综合考虑硫化矿物的总体解离效果,建议在实际生产时选用磨矿细度为-200目占70%左右时的磨矿工艺。

Comprehensive studies by means of polished thin section method , X -ray diffraction , X -ray en-ergy as well as chemical analysis and chemical phase analysis were made which result in an understanding of the mineral components of ore and the occurrence state of Cu -Co elements at Baluba deposit . On the basis of exploration data , correlation diagram and correlation coefficient were applied to get a conclusion that the positive correlation between Cu and Co elements at Baluba deposit .
