| 摘 要： | 据地质勘探资料并结合显微镜观察、X衍射和差热分析法,研究了陕西府谷地区煤层中的煤矸石赋存状况。结果表明:府谷地区的煤矸石赋存丰富,且大多数样品中高岭石的质量分数均在90%以上,可作为优质的高岭土矿产。对该煤矸石的煅烧增白研究表明,在相同的煅烧条件下,含碳量高的煤矸石白度提高得快。

| Abstract: | The occurrence of waste of coal in Fugu area,Shaanxi Province are analyzed based on geological exploration data,combined with mirco-observation,x-ray diffration method and different thermal analyse method.The results indicated that in this area the waste of coal is rich and the mineral contents in most samples are dominated by kaolinite(>90%).The analysis of calcination for white-increasing shows that under the same calcination conditions the higher carbon coal waste is of high speed for white degree increasing. |
