PURPOSE:To reduce the cost for copper refining by heating crosslinked PE powder as an energy source in the stage of continuously refining and converting copper concentrate by a furnace of a reflection furnace type. CONSTITUTION:The powder or chips of the crosslinked PE are used as the energy source in the stage of continuously refining and converting the copper concentrate by using the furnace of the reflection furnace type. The grain size of the crosslinked PE is preferably specified to <=5mm. A burner which is made into a cylindrical body by fitting a semi-cylindrical male body 7 and female body 8 and is provided with an adjusting screw 9 in the fitting part is used for the burner to be used for heating and is so constructed as to permit the fine adjustment of the flying distance of the crosslinked PE so as to attain an adequate position by deforming the sectional shape thereof. Welding of the crosslinked PE is prevented by providing a jacket 5 to the burner and cooling the same.
