| Abstract: | The content of Gallium in gangue from the main coal-producing area Zhijin, Nayong, Jinsha and Dafang in Bijie was determined by Spectrophotometry, and chromogenic reagent is Rhodamine B. The re-sults show that the content of Ga in gangue is higher than the economic threshold 30ppm, and it is in line with national industrial use of grade requirements. Among them, the content of Ga is 43.5ppm in gangue from Feng-hepingqiao of Zhijin, and 41.4ppm from Hongtu of Nayong, which are of high value of extracting. |
