Study of Extracting Gallium from Shuangyashan Iron Mine Containing Gallium

The valuble gallium contained in Shuangyashan iron ore couldn't be used as raw material because of a low content of gallium.A possible way to extract gallium from ore dusts was given.The leaching rate of gallium could reach 68.74% on the conditions:the leaching temperature was 95 ℃,the solid liquid ration was 1∶4, more than 76.70% material,the diameter of which was below 0.074 mm.
