In response to the issues of high pollution,high losses,high energy consumption,and high costs in traditional gold electrolytic refining processes,green and environmentally friendly technologies such as ion exchange membrane electrolysis,powder metallurgy,wet ammonia-free processes,and the use of Ag-Ti bimetallic composite materials were introduced.This enabled the improvement of quality and reduction of consumption throughout the entire process of gold electrolytic refining,from ingot casting,solution preparation,electrolysis,to the purification of spent electrolytes and gold anode slime treatment.The successful application of this technology increased the gold recovery rate from 99.85 % to 99.95 % and the silver recovery rate from 66 %  to 99 %,while reducing energy consumption by about 30 %.It effectively eliminated the generation of nitrogen oxides and the use of ammonia water from the source,bringing significant economic and environmental ecological benefits to enterprises.
