METHOD OF REMOVING SCULL IN COPPER-REFINING FURNACES

摘要

The invention is intended to remove scum in metallurgical furnaces, for example, copper refining. The aim of the invention is to increase the recovery of copper in finished products by reducing the yield of revolutions and. increase in the overhaul campaign of stoves. Rough copper is poured into the furnace. A carbon-hydrogen-containing reducing agent is fed to the copper melt until the nickel concentration in the blister copper is increased. The temperature of the melt is maintained in the range of 1200-1280. 1 tab.
