Occurrence characters of waste of coal in Fugu area and propertie of white-increasing through calcination

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.
