20080264209 | METHOD AND SYSTEM FOR INJECTING GAS INTO A COPPER REFINING PROCESS - A method for refining copper wherein a stream of oxygen containing gas is provided from a lance into the headspace of a refining vessel for passage to the molten copper bath within the refining vessel, and a flame envelope is provided around and along the oxygen containing gas stream for a portion of its length, wherein the flame envelope simultaneously serves to keep accretions from forming on the lance face and serves to maintain the oxygen-containing gas stream coherent. | 10-30-2008 |

20090325110 | RELIABLE IGNITION OF HOT OXYGEN GENERATOR - A stream of hot oxygen is formed by providing a duct and a fuel lance movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet approaches the duct exit orifice so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant. | 12-31-2009 |
20120036963 | COPPER ANODE REFINING SYSTEM AND METHOD - 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 NO | 02-16-2012 |
