The invention relates to a method for concentrating gold from pyrite inclusion-type gold ore. The pyrite inclusion-type gold ore is gold-containing sulfur ore with high recovery value. The roasted ore of pyrite inclusion-type gold ore is used as raw material and proportionally mixed with charred coal, lime and quartz; and the resulting mixture is fed into a smelting furnace and undergoes the reduction smelting at a temperature ranging from 1450 DEG C to 1600 DEG C, so as to produce gold-rich pig iron. The gold-rich pig iron as an anode plate is electrolyzed by the diaphragm electrolysis technique in an electrolysis system containing ferrous sulfate or ammonium sulfate aqueous solution, so as to produce electrolytic iron and gold-rich anode mud. The method increases the resource utilization rate and is environment-friendly.
