Title: Method for continuously blowing materials into molten slags

Abstract: A metallurgical method and apparatus; air is continuously blown into a mixture of agglomerates of lead concentrates and carbonaceous fuel in a shaft furnace. The resulting slag is delivered from the shaft furnace into a settling tank to which the slag continuously flows while the slag is continuously delivered from the settling tank into a fuming furnace, so that the slag flows in cascade from the shaft furnace to the settling tank and from the settling tank to the fuming furnace, thereby providing a continuous flow of the treated slag from the shaft furnace through the settling tank into the fuming furnace; the slag, in addition, is continuously withdrawn from the shaft furnace.
