Research of Leaching and Separation Experiment on Gallium from Gallium-rich Material AITranslate
Abstract AITranslate
The experimental study was conducted on NaOH leaching and ion exchange separation of gallium -rich material obtained by concentrate roasting-calcine sulfuric acid selective enriching of alunite. The re- sults show that during the NaOH leaching, the gallium leaching rate can reach 98.84% under the conditions of 75 % NaOH concentration, 15 rain leaching time, 3 ： 1 liquid-solid ratio, 300 r/min agitating velocity. During the ion exchange,the gallium adsorption rate is 71.4% under the conditions of the NaOH concentration of 150 g/L in adsorbed solution,Rexp-31 resin dosage of 150 g/L,spray rate of 5 mL/min,resin bed height of 15 cm. The gallium desorption rate can is 88.16% ,under the conditions of NaOH and Na2S concentration in the desorption agent of 160 g/L and 50 g/L,respectively, liquid-solid ratio of 10 ：1, de- sorption duration of 1 h.
