Process for reducing content of suspended matters in gallium metal adsorption mother liquor

The invention discloses a process for reducing the content of suspended matters in metal gallium adsorption mother liquor, and relates to the technical field of metallurgy, the process comprises the following steps: S1, filtering and purifying mother liquor in a seed precipitation mother liquor storage tank; s2, feeding the net seed mother obtained in the step S1 into a first net seed mother tank, and returning a filter cake to an aluminum oxide system; s3, performing overflow treatment on the mother liquor in the first seed cleaning mother tank by using an overflow treatment device, and feeding the finally obtained mother liquor to an adsorption tower for resin adsorption; and S4, after the overflow treatment device runs for a preset time, returning the first seed cleaning mother tank and the bottom material subjected to overflow treatment to the aluminum oxide system. The suspended matter in the mother liquor stays in the first seed cleaning mother tank and the overflow treatment device for a certain time,
