The invention provides an efficient smelting and separating device for complex copper-lead-zinc-gold metal mineral resources. A convex area is arranged at the side end of a furnace body; a furnace cavity is internally composed of a copper matte smelting separating region and a slag smelting separating region; a charge hole and a flue gas hole are formed in the upper portion of the copper matte smelting separating region; a copper matte discharge hole is formed in an end wall without a convex area; a slag discharge hole is formed in an end wall with the convex area; a plurality of oxygen lance insertion holes are formed in the bottom of the copper matte smelting separating region, and 1-25 oxygen lances are arranged with spacing of 0.5-1.3 meters; and a plurality of oxygen lance insertion holes are formed in the side part of the slag smelting separating region, and 1-5 oxygen lances are arranged with spacing of 0.5-1.3 meters. The efficient smelting and separating device has the advantages that: metal elements such as copper, lead, zinc, arsenic, bismuth and antimony in complex metal minerals can be separated in a smelting process; molten-stage copper matte is good in continuous emission performance; copper matte discharge amount is controllable; a copper placing hole does not need to seal by a stemming machine; investment is less; and labor intensity of a worker is small.
