The gold ore associated in Haxiyatu iron-polymetallic deposit has reached medium-scale，which can greatly improve the economic efficiency of the iron-polymetallic deposit.Research on comprehensive recovery and utilization method of gold ore is very important.The gold ore belongs to the sulfide skarn type，with the natural type belonging to the mixed ore.The metal minerals in the ore are dominated by magnetite，pyrrhotite and pyrite，and noble metal minerals are native gold and electrum.Through the experiment，the flotation process scheme is recommended that “gold flotation，tailings magnetic iron and iron concentrate flotation sulfur”.Leaching process scheme is recommended that“all sliming cyanidation carbon leaching，tailings magnetic separation iron and iron concentrate flotation sulfur”.According to the test results，the process by all sliming cyanidation carbon leaching and magnetic iron （remove sulfur by floating） can obtain better effect.
Key words： ore properties; flotation; magnetic separation; Haxiyatu
