PROBLEM TO BE SOLVED: To provide a method where, in a flash smelting furnace provided with a mineral concentrate burner for blowing a smelting raw material and a gas for reaction, the degree of premixing in a burner cone between the flow of the gas for reaction and the smelting raw material is controlled, by which their smelting reaction in the flash smelting furnace within the mineral concentrate burner, a reaction tower or the like is controlled. SOLUTION: Using a mineral concentrate burner comprising: a movable wind speed regulator; a movable mineral concentrate chute; a wind box into which a manometer is incorporated; and a burner cone, for controlling the degree of premixing between a smelting raw material and a gas for reaction in the burner cone, the position of the wind speed regulator and the position of the mineral concentrate chute are regulated, respectively, thus the pressure in the wind box is controlled to a previously selected prescribed value.
