COPPER ANODE REFINING SYSTEM AND METHOD |
摘要 |
A method and system for the copper anode refining is provided in which coherent jet technology is employed to heat the molten blister copper and/or melt scrap copper charges using a melting flame, oxidize the sulfur in the molten blister copper, and reduce the oxygen in the molten blister copper using top-blown coherent jet gas streams from one or more multi-functional, coherent jet lance assemblies. The present system and method employs a microprocessor-based controller operatively controlling the flow of an oxygen-containing gas, an inert gas, a reducing agent and a fuel to the coherent jet lance. The disclosed copper anode refining system and method greatly improves copper production while lowering oxidation /reduction cycle times and minimizing NOx emissions. |
