PROBLEM TO BE SOLVED: To provide a converter operation method for improving the productivity of crude copper by increasing a quantity of white matte in a step of manufacturing copper through increasing the quantity of the molten matte to be charged into a converter, and by preventing a blowing-up phenomenon of the white matte owing to blowing of an oxygen-containing gas. SOLUTION: The converter operation method for manufacturing crude copper through accommodating the molten matte in the converter 1 and blowing the oxygen-containing gas, comprises oxidizing the molten matte in the converter by blowing the oxygen-containing gas to separate it into the white matte and slag, removing the slag, further discharging 20 to 30 mass% of the white matte from the converter, blowing the oxygen-containing gas into the white matte in the converter for 30 to 120 minutes, then returning the white matte once discharged from the converter into the converter, and blowing the oxygen-containing gas.
