Abstract: Disclosed in the present application is a copper rotation-suspension smelting process comprising: mixing a flux and/or fume with dried copper-containing mineral powders to form a mixed material, which enters into a smelting furnace through a material channel; allowing a reaction gas to form a swirling flow under an action of a swirler, which enters into the smelting furnace through a Venturi channel under a guidance of a swirling gas channel; replenishing the reaction gas and/or a fuel to the smelting furnace through an auxiliary oxygen channel and an auxiliary fuel channel; subjecting the swirling flow which has been subjected to high-speed expansion through the Venturi channel and enters into the smelting furnace to a contact reaction with the mixed material; separating a melt generated by the reaction which falls into a settling tank into a residue layer and a copper-containing product layer.
