青海某低品位铁矿的工艺矿物学研究
Study on Process Mineralogy for Some Low-grade Iron Ore in Qinghai
摘要
Abstract
According to the process mineralogy study on low-grade ores from a metamorphic iron deposit,the results show that the ores are characterized by low iron,high silicon,low phosphorus and low sulfur.The types of the iron minerals are complex which include dominant magnetite as well as minor siderite and hematite,and the grain size of the iron minerals is fine.The iron minerals have a very complex embedded relationship with the gangue minerals containing silicon,especially with the fine chlorite and the iron minerals.Based on the process mineralogy research,the key reasons of refractory have been emphatically analyzed,and the mineralogy reference is provided for the development and utilization of the low-grade metamorphic iron ores.关键词
