摘要： The present specification discloses a pyrometallurgical system for maintaining a material in a molten state, the system comprising a vessel for molten material, the vessel conceptually dividable into a number of substantially uniform cells. A mechanical stirrer is provided for each such cell and is centered within the cell. The stirrers are sized and driven at a rate so as to promote a uniform temperature and composition of the molten material and improved heat transfer between, and blending of, various constituents of molten material, while producing minimal erosion of the conventional refractory lining of the vessel. Preferably, adjacent pairs of stirrers are driven with opposite rotational senses, thereby assuring reinforcing flow patterns at the cell boundaries. Heating means (e.g., power electrodes) are provided at locations which do not substantially interfere with the flow patterns generated by the array of mechanical stirrers.

摘要： A process for recovering iron from preliminarily decopperized molten copper smelter slags having an initial composition which includes iron oxide, silica, and aluminum oxide as the major constituents. These constituents are initially present in the range of 40-70 percent FeO, 25-40 percent SiO.sub.2 and 5-10 percent Al.sub.2 O.sub.3. The slag is maintained in a molten state and a solid reductant is mixed into the slag using an internally cooled, metal bladed, rotating stirrer, which rotates at a rate sufficient to pump the reductant into the slag to enhance the reduction of the iron oxide. An important aspect of this invention is to reduce slag to recover iron when the slag contains the following constituents, 40-60 percent SiO.sub.2, 15-35 percent CaO, less than 20 percent FeO and 5-10 percent Al.sub.2 O.sub.3. Although the above constituents can vary within the range set forth, it is important to maintain the SiO.sub.2 to CaO ratio in the range of about 2.0 - 3.3. Thus, along with the reducing agent, other constituents are added to the molten slag to maintain the slag with the desired composition set forth above. After reduction of the slag in accordance with the foregoing procedure, the iron bearing phase is separated from the slag in the form of a metal-rich matte containing 85-90 percent iron.

摘要： Molten molybdenum-(copper)-iron-sulfur mattes or alloys, obtained for example, by reacting slags or other molybdenum containing oxide residues or waste materials with an iron and/or sulfide reductant, are enriched in molybdenum and copper (if present) by a pyrometallurgical process. The molten matte or alloy material is oxidized to remove sulfur, as sulfur oxides, while varying amounts of iron are converted to iron oxides which separate from the metallics. The oxidation thus enriches the molybdenum and copper content of the remaining alloy. Silica flux may be added during the reaction process to form a fluid slag with the iron oxide which separates from the remaining molybdenum-iron-(copper) material which constitutes the product.

摘要： Process for recovering nickel and nickel-copper from molten smelter-type slags or other highly oxidized sources of nickel and nickel-copper containing 7 to 30 percent by weight of magnetite (Fe.sub.3 O.sub.4). The magnetite in the slag is reduced with carbonaceous materials or other solid reductants such as sulfides, metals or carbides. While the slag is mixed with a fluid cooled, metal-bladed mechanical stirrer, the reductant is reacted with the slag. As a result of stirring the reductant into the slag, the rate of magnetite reduction is highly accelerated. With the reduction, the nickel or nickel-copper (as well as cobalt, if present) separates into a phase as either immiscible metal, a sulfide, or a nickel-copper-iron-sulfide matte, depending upon the initial composition of the slag.
