Abstract

PURPOSE: To reduce the consumption of a lance pipe attached to a smelting furnace and the damage of the inner wall of the furnace due to splash by specifying the attaching angle of the lance pipe to the furnace when sulfide ore of copper is smelted to crude copper after producing matte.
CONSTITUTION: Starting material sulfide of Cu is smelted to crude copper after producing Cu matte, and crude coppper as starting material for electrolytic copper is manufactured. At this time, a lance pipe 11 is attached to the side wall 20 of a smelting furnace 2 at θ(38W42°) angle to the surface of molten metal so that the tip of the pipe 11 is located at (h) (100W200μm) height from the surface of the metal. Powdered starting materials such as fine Cu ore and silica sand are blown into molten metal 3 from the lance together with air or gaseous oxygen and smelted to crude copper. Thus, the damage of the inner wall of the furface due to splash 14 formed by blowing from the pipe 11 is reduced extremely besides the damage of the lance pipe 11 itself by melting.
