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.

摘要： A system, device, and method include a cell-powered first electronic device powered using electrical potential imposed across an electrolytic cell. The potential is voltage-boosted to accomplish this task. If the electrical potential imposed the cell is insufficient, the device can also be battery-powered. In any event, this device is in communication with one or more sensors in the electrolytic cell, as well as a second electronic device, and the first and second electronic devices wirelessly communicate. More specifically, the first electronic device wireless transmits data signals to the second electronic device, which receives the same. The first and second electronic devices are physically remote from one another, and they communicating over a private or public network, preferably using spread spectrum technology. In addition, the second electronic device also preferably transmits data signals to a computer for further processing of the data signals, and these arrangements can be used, for example, when producing copper.

摘要： Molten matte or slag is water granulated by feeding molten matte or slag through a launder to a granulator tank. The tank includes sloping walls and is equipped with adjustable overflow weirs and one or more of spray nozzles. These nozzles are positioned such that the water that they emit impacts on substantially all of the molten matte or slag that is fed to the granulator tank. The granulation tank is optionally coated with a polymeric material to reduce the potential for phreatic explosions. The granulator is also optionally equipped with a gas offtake which can be connected directly to a quench tower which in turn can be connected to an induced ventilation system.

摘要： Copper sulfide ores are processed by a unique series of steps to produce blister copper, while attaining long sought advantages. An initial smelting step is carried out in any desired manner, e.g. according to conventional practice, to produce a molten, copper sulfide matte or white metal. This matte or white metal is then solidified and subjected to a size-reduction step to produce solid particles capable of being injected into a converting vessel in a stream of oxygen, either pure oxygen or air significantly enriched with oxygen. With the matte or white metal injected in this manner, the converting reaction may be carried out on an autogenous basis, with continuous evolution of substantially undiluted SO.sub.2 gas capable of being liquified for use in the production of elemental sulfur or sulfuric acid or for disposal so as to avoid atmospheric contamination. The usual fugitive gas emissions resulting from the handing and transporting of molten matte in conventional ways are almost completely avoided, and continuous optimized operation of the converting vessel is achieved independently of operation of the smelting step, making it possible to eliminate the often-resorted-to close coupling of smelting and converting furnaces and affording unusual freedom in plant layout.

摘要： Impure copper precipitates, obtained by cementation of copper from an aqueous solution, are converted into dense, unfriable, high-grade copper pellets suitable for separate smelting and refining as well as for being fed directly to anode or refining furnaces. Sufficient water is added to the copper precipitates to form a coherent, moldable mass of moist precipitates, which is then formed into pellets. The pellets are dried, and then heated to a sintering temperature of at least 750.degree. C. in a reducing atmosphere. The pellets are held at the sintering temperature for a time sufficient to form dense, unfriable, high-grade copper pellets, and the high-grade pellets are then cooled to near ambient temperature before being exposed to an oxidizing atmosphere such as air.

摘要： For an electrolytic cell, an apparatus and method are described that use one or more sensors to measure magnetic field strength about a conductor carrying electrical current. A processor is in electrical communication with the sensors and determines a compensated magnetic field strength based on the magnetic fields of other conductors that also carry electrical current to or from the electrolytic cell. The processor uses this compensated magnetic field strength to determine the cathode electrical current carried by the conductor and to identify open and short circuits between the anodes and cathodes of the cell. The described apparatus and method account for interactions between the magnetic fields of the neighboring cathodes.

摘要： Metal, e.g. copper, is electrolytically deposited within the recess formed over a plugged hole of a component of a pyrometallurgical vessel, e.g. a cooling block, to form a seamless seal with the surface of the component. The method comprises the steps of inserting a mechanical plug into a channel opening of the component such that a recess is formed between the external surface of the plug and the outer surface of the component; positioning an anode adjacent the recess; providing an aqueous solution containing metallic ions, e.g. a solution of copper sulfate, between the anode and the mechanical plug; and creating an electric potential across the anode and the mechanical plug such that metal is deposited within the recess, preferably until the recess is filled with the electrodeposited metal. In alternative embodiments, the process can be used to secure fittings and the like to the components or to repair ruptured or weakened areas along the perimeter of such fittings.
