【Abstract】 The effect of immersion and digestion of gallium in bauxite by HCl is studied in this paper with the results of a series of conditional experiments. The results show that under the condition of 500 ℃ , samples of bauxite are calcined for three hours, then immersed in HCl solution when concentration is 6 mol/L , and digested for twelve hours, with its ratio of solid to liquid being 1∶2.5. In this way, the ratio of digestion to total gallium in bauxite is beyond 94%.更多还原
