这是一篇矿业工程领域的论文.矿物的工艺矿物学性质是选矿工艺的前提,查明矿石细度、目的矿物单体解离度等对矿石可浮性的影响,可为选择合适的浮选条件提供指导.为此,通过 X射线荧光分析、X射线粉晶衍射分析、扫描电镜和偏光显微镜等分析手段对某铜钴矿石进行了系统的工艺矿物学研究.在工艺矿物学研究的基础上,对该铜钴矿采用在磨矿细度-0.074 mm 70%的条件下,按照一粗两扫两精的浮选流程开展闭路实验,获得铜品位21.04%、钴品位 9.83%,铜回收率92.88%,钴回收率92.84%的硫化精矿产品.
Effect of Process Mineralogical Properties on Floatability of a Copper-cobalt Ore in Zambia
This is an article in the field of mining engineering.The process mineralogy is the prerequisite for flotation.The influence of ore fineness and the degree of dissociation of the target mineral monomer on ore floatability can be used to guide the selection of suitable flotation conditions.A systematic study of the process mineralogy of a copper-cobalt ore was carried out using the methods of X-ray fluorescence analysis,X-ray powder diffraction analysis,scanning electron microscopy,and electron polarizing microscopy.Based on the process mineralogy studies,the flotation tests were carried out,at the condition of grinding fineness of-0.074 mm 70%,with a process of one roughing-two scavenging-two cleaning closed-circuit flowsheet.The sulfide concentrate with the grade of Cu 21.04%,Co 9.83%and the recovery of Cu 92.88%,Co 92.84%was achieved.
