Objetivo THE OBJECTIVE OF THE PROJECT IS TO REDUCE THE ENERGY REQUIREMENTS FOR THE PROCESSING OF NON-FERROUS HEAVY-METAL SLAGS BY THE COMBINED USE OF A SUBMERGED ARC FURNACE AND THE SUBMERGED INJECTION OF COAL. IN TERMS OF QUANTITY, COPPER AND LEAD ARE AMONG THE MOST IMPORTANT NON-FERROUS METALS. MOST SUCH METALS ARE PRODUCED TODAY FROM SULPHIDE ORES/ORE CONCENTRATES. FOR A VARIETY OF REASONS, MODERN METHODS OF PROCESSING THESE RAW MATERIALS HAVE A HIGH OXYGEN REQUIREMENT AT THE PRIMARY MELTING STAGE. AS A RESULT OF THIS HIGH OXYGEN REQUIREMENT, THE PRIMARY SLAGS PRODUCED HAVE AN UNACCEPTABLY HIGH CONTENT OF VALUABLE METAL, MAKING SUBSEQUENT METAL REMOVAL IMPERATIVE. THE USE OF ARC FURNACES FOR SLAG REQUIRES MORE ENERGY THAN NORMAL PROCESSING BUT OFFERS THE ADVANTAGE OF A HIGHER OVERALL YIELD IN USABLE METALS. ALTHOUGH IT IS THE STATE OF THE ART, THE USE OF ARC FURNACES IS GENERALLY HELD TO BE UNSATISFACTORY FROM A METALLURGICAL POINT OF VIEW, SINCE THE SPEED OF THE CHEMICAL REACTION IS COMPARATIVELY LOW AND THERE ARE FEW POSSIBILITIES OF EXERTING AN INFLUENCE ON THE METALLURGICAL PROCESS. THE AIM OF THE PROPOSED WORK IS TO REDUCE THE ELECTRICITY AND ELECTRODE CONSUMPTION OF THE PROCESS BY INJECTING COAL AND OXYGEN DIRECTLY INTO THE SLAG BATH.
