The method has the advantages of simple equipment, convenient operation and high automation degree.

Description

technical field [0001] The invention relates to a continuous ion exchange device, in particular to a continuous ion exchange device for extracting gallium from Bayer mother liquor, and also relates to a continuous ion exchange method for extracting gallium from Bayer mother liquor by using the device. Background technique [0002] Gallium is a kind of scattered metal, which has important uses in the semiconductor industry. With the development of semiconductor technology, the demand for gallium metal is increasing day by day. The sources of metal gallium are scarce, and its products mostly come from by-products such as the aluminum industry. The production of metal gallium by the resin method has become the main way to extract metal gallium from the alumina production process. In the traditional fixed bed process, due to the continuous deposition of aluminum hydroxide floats in the resin, the resistance of the solution increases, thereby reducing the throughput and seriousl...
