Abstract
Available silicone was melted from coal gangue samples from Hancheng diggings through calcination digestion and other means The best calcination temperature was determined from a range of 550∼1 150 °C and the best time from a range of 05∼5 h by colorimetry method The proper ratio of coal gangue limestone sodium carbonate and caustic soda was then determined through orthogonal experiment The results show that the proper extraction condition for available silicone is the ratio of coal gangue limestone sodium carbonate and caustic soda at 10501005 calcination temperature at 700 °C and calcination time at 2 h In this condition the available silicone content can be more than 1965
