摘要
对贵州毕节地区煤矸石的特征进行分析,结果表明:煤矸石的矿物组成以石英和高岭石为主,同时含有较多的蒙脱石、伊利石、菱铁矿、斜长石、黄铁矿、白云石及锐钛矿;SiO 2、Al 2O 3和Fe 2O 3三者总含量占煤矸石的50%~75%;煤矸石中微量元素V、Co、Ni、Gr、Ge的富集程度较高。根据分析结果,毕节地区煤矸石以中低碳、少低硫、富中铁型为主,大部分煤矸石固定碳含量及发热量较低,不适宜能源方面的利用。
The characteristics of coal gangue from Bijie,Guizhou were studied.The results show that coal gangue mainly consists of quartz and kaolinite,as well as montmorillonite,illite,siderite,plagioclase,pyrite,dolomite and anatase.The total content of SiO 2,Al 2O 3 and Fe 2O 3 in coal gangue is up to 50%to 75%.The concentration of V,Co,Ni,Gr and Ge is high in coal gangue.In conclusion,coal gangue from Bijie is featured by mid-low carbon,low sulfur and mid-rich iron,with low carbon content and low calorific value,which is not suitable for power generation utilization.
