摘要
中低品位磷块岩已成为我国磷资源利用的主要来源,对其合理的利用才能实现磷资源工业的可持续发展,对矿石进行工艺矿物学研究则是实现其合理利用的基础.通过化学分析、光学显微镜下分析、测定等方法对弥勒天裕中低品位磷块岩进行了工艺矿物学研究.结果表明矿石的工业类型为硅质磷块岩,其有用矿物为胶磷矿,脉石矿物有石英、玉髓、白云石,少量铁泥质岩屑、长石、云母、电气石等,均为细粒嵌布,当磨至-0.074 mm时,93.28%的胶磷矿和脉石矿物解离,解离性良好.
The mid-low grade phosphate rock has become one of the main sources of phosphorus resources,only to utilize this kind of phosphorus resource can grantee the sustainable development of phosphorus chemical industry,and research for mineralogy of the ore is the basis for its use.We have researched the Process Mineralogy of the mid-low grade phosphate rock of Yunnan Mile Tianyu by chemical analysis,optical microscopy analysis,determination and other methods.The results show that the ore is the siliceous ore in industry,and that phosphate rock is the useful minerals and gangue minerals are quartz,chalcedony,dolomite and a little of iron muddy debris,feldspar,mica,tourmaline,etc.Most components of the ore are Fine-grained disseminated.93.28% of the phosphate rock and gangue minerals are dissociated when the ore is milled to-0.074 mm.Dissociation of the ore is good.
