The application provides an amino acid composite reagent system and a method for treating electronic waste to prepare high-purity glycine copper, and belongs to the technical field of metal hydrometallurgy and resource recycling. The application builds an ammonia catalytic reduction mechanism by designing an amino acid composite reagent system, greatly improves the leaching rate, simultaneously inhibits the dual effects of copper hydroxide precipitation and glycine chelation, and realizes efficient solution of copper ions; through narrow window regulation technology of pH at 9.5±0.2, the stability of ammonia, the activity of glycine anion are maintained, and the selective leaching rate of copper is ensured; a directional crystallization process of leaching solution is constructed, the "self-assembly directional crystallization" process of glycine copper chelate is used, based on the saturation concentration of glycine copper in the leaching solution and the stable chelate structure, through three-stage crystallization precise regulation, the preparation of high-purity crystal is realized. The process realizes the closed-loop crystallization system of "zero addition of crystal seeds and zero wastewater discharge" of the copper-containing complex leaching solution of electronic waste.
