The invention discloses a method for recovering silver in a jamesonite waste residue. The method for recovering the silver in the jamesonite waste residue comprises the following steps of (1) pressurizing and oxidizing: heating, stirring, pressurizing and oxidizing under an oxygen atmosphere; (2) digesting and filtering: injecting a digestion solution, heating, stirring to completely digest the waste residue, adding a regulator for regulating a pH value after digesting completely, and filtering to obtain a filter liquor; (3) reacting and settling: adding compound protease and a silver ion intothe filter liquor, combining, pressurizing, filtering the solution obtained after reaction through a semipermeable membrane, and separating to obtain a protein silver mud; (4) hydrolyzing and acidifying: adding a hydrolysate into the protein silver mud, heating for hydrolyzing, acidifying through dilute nitric acid to form a silver-rich solution after hydrolyzing, and adjusting a pH value of thesilver-rich solution; and (5) electrolyzing and purifying: adopting an ion exchange membrane for carrying out diaphragm electrolysis in an electrolysis bath used by a diaphragm electrolysis process, and precipitating pure silver on a cathode electrode. The method for recovering the silver in the jamesonite waste residue provided by the invention is simple to operate, easy to implement, low in labor cost, and beneficial to reducing manual labor intensity, and improving working efficiency.
