This invention discloses a method for recovering platinum and palladium from the gold extraction solution of silver anode mud. Bismuth is removed through a two-stage hydrolysis process using ferric chloride and sodium hydroxide at room temperature and boiling conditions, achieving highly efficient bismuth removal while avoiding simultaneous hydrolysis loss of precious metals. The bismuth removal efficiency can reach over 96%. A purification agent, primarily sodium diacetate, is added to the bismuth-removed solution to form insoluble metal salts with base metal ions such as nickel, copper, and iron, thus purifying the solution. This agent does not react with platinum and palladium in the solution, preventing any loss of platinum and palladium metals. An organic amine precipitant is added to the copper and nickel-removed solution. The C2H8N2 and C3H8ClN in the precipitant react with high-valence platinum in the solution to form organic amine platinum salts, while the high-valence palladium in the solution does not form salt precipitates, thereby separating platinum and palladium. The separated organic amine platinum salts are then used for platinum refining to produce qualified platinum products, and the palladium-containing mother liquor is used for palladium refining via a complexation acidification process to produce qualified palladium products.
