The invention discloses a method for efficiently concentrating precious metal from a difficultly-treated palladium-containing waste catalyst. The method includes the steps that the palladium-containing waste catalyst, copper mud pressurizing slag, a reducing agent and a fluxing agent are heated and subjected to heat insulation; slag and a precious lead alloy are subjected to cooling separation, grinding is conduced, and sampling analysis of the content is conducted; vacuum melting distillation separation is conducted on the precious lead alloy, a vacuum furnace rare and precious alloy and a lead bismuth alloy are obtained, and the precious metal is separated from lead and bismuth. By means of the method, a melting low-temperature alkaline concentration smelting method is used for treatingthe high silicon and aluminum carrier type high and low grade palladium-containing waste catalyst and the copper anode mud pressurizing slag, gradient comprehensive utilization of gold, silver and platinum family precious metal, lead, bismuth and dissipated, rare and precious metal elements is achieved, the process is the shortest, the cost is the lowest, and efficiency is the highest. The palladium-containing waste catalyst rate can be large and can be small, the treatment capability is flexible, concentration smelting treatment is achieved, and concentration smelting of the palladium familyprecious metal is not affected; and a melting low-temperature alkaline smelting technology is adopted, the smelting temperature is far lower than that of matte smelting, energy consumption is greatlyreduced, and therefore the machining cost of the difficultly-treated waste catalyst is reduced.
