To provide a method for charging an ore to be charged into a flash smelting furnace, which can inexpensively and accurately regulate the charging amount of ore, and can stabilize the mat grade.

In the method for charging an ore to be charged into the flash smelting furnace, which cuts out the ore 30 into a fixed volume, carries it by a chain conveyor 12 and drops it in a chute 14, and charges it into the flash smelting furnace 1 with an oxygen-enriched air 40 from a concentrate burner 9 at the outlet of the chute, a flowmeter 15 is installed on the way to the chute, which converts a change of the capacitance detected when particulate matters pass between capacitor plates, into a flow rate of the particulate matters; the falling flow rate of the charged ore in the chute is measured with the flowmeter; and the revolution speed of a motor 13 for the chain conveyer is regulated so as to make the measured flow rate of the charged ore match with an aimed charging quantity. And also, a shutter 17 for opening/closing the chute is installed on the outlet side of the installed flow meter, and it is opened during charging and closed during the rest time.
