摘要： A process for manufacturing nuclear radiation shields consisting of neutron-absorbing boron carbide particles embedded in a heat-dissipating copper matrix. Copper is electroplated through a layer of loose, electrically nonconductive boron carbide particles on a metal substrate. The carbide particles may be deposited on the substrate while electroplating, and heat exchanger ductwork may be incorporated. To make cylindrical shields, a cylindrical metal substrate is rotated about its axis giving rise to centrifugal forces which hold the carbide particles on the inner surface and aid electrodeposition. A thermomechanical process is described in which boron carbide particles pre-encapsulated with copper are consolidated into a unitary mass on the inner surface of a heated cylindrical substrate with or without the aid of a roller within the cylinder.

摘要： Bearing assemblies for supporting cylindrical, metal-rolling rolls. The bearings are housed in chock blocks and comprise both radial and thrust bearings. The radial bearings are hemi-cylindrical in shape and extend around approximately one half of the circumference of each roll and make contact with the surface of each roll thereby minimizing lateral roll deflections. A thrust bearing engages a fraction of the surface of at least one end face of each roll. Both the radial and thrust bearings are preferably made of high strength, mechanical graphite or carbon.

摘要： Apparatus for guiding and coiling one or more metallic strands that are continuously advancing along their length from a casting apparatus. A coiling apparatus has an open-top coil-collecting basket with concentric, generally cylindrical inner and outer walls. A rotating cone is disposed over the inner wall. At least one boom and a set of opposed rolls and associated fairing assemblies mounted on the boom guide the strand from the casting apparatus to the coiling apparatus. An exit end of the boom directs each strand vertically downward onto the cone of one coiler. Friction between the strand and the cone lays the strand in the basket in horizontal wraps without a reversal of the laying direction or kinks. The boom exit end mounts a straightener that includes a pair of hydraulically-actuated slide bars that are orthogonal to each other and to the strand. The slide bars produce a cyclic deflection of the strand about the center of the cone to form a uniform, non-tangled coil. The cone-straightener spacing and the cone angle are selected to produce a bend radius in the strand such that the coiled strand does not climb the inner or outer walls of the basket. The diameter of the inside wall is large enough so that the horizontal wraps collapse on one another of their own weight. The boom is hollow and has a series openings adjacent the strand to direct cooling air from the interior of the boom to the strand. In one form the boom has a generally rectangular cross section and carries strands on two vertical walls. A second exit end, positioned midway along the boom directs one strand to a second coiler.

摘要： A process for improving overall recovery of copper from an integrated mining and metallurgical processing operation by utilizing iron-containing copper ore materials as mined, such as low-grade copper ores and mine wastes, and crushed or granulated copper-containing slag obtained by smelting the higher-grade portions of such ore materials, involves the minign of such ore materials, the smelting of higher grade portions thereof, and the leaching of copper values from lower grade portions thereof with an aqueous, weakly acidic lixiviant to produce an acidic, ferric, effluent solution. The smelter slag is leached with the such effluent solution and copper values are recovered from the resulting pregnant solution. If desired, the barren solution may be recycled to the initial ore leaching step. By maintaining the pH of the acidic, ferric effluent solution from the initial leach within its normal range of about 1.9 to 3.0 for the slag leaching step, copper is selectively leached from the smelting slag while avoiding the usual precipitation of ferric salts and the formation of gelatinous slag decrepitation products. Moreover, ferric ion values in the acidic, ferric effluent solution from the initial leach are significantly reduced during laching of the smelter slag, thereby significantly increasing the efficiency of copper recovery in a subsequent step of either cementation of copper on metallic iron or electro-winning of copper.

摘要： A novel class of extractants and a method of using the extractants in the hydrometallurgical recovery of nickel and cobalt metal. The extractants comprise a water immiscible organic solvent system containing solubilized mercaptide anions. In an important embodiment of the invention, the mercaptide ions are generated by adding a mercaptan to a mixed water immiscible solvent comprising a basic compound such as an amine, preferably a tertiary amine, and a polar component such as an alcohol, whereby the mercaptan undergoes acid dissociation.The extractants are used by being contacted with cobalt, nickel, or cobalt and nickel containing aqueous solutions. On mixing, the cobalt and/or nickel values are taken up by the organic as cobalt or nickel mercaptides. These may then be stripped of cobalt and nickel by treatment with an aqueous alkaline solution and carbon monoxide.

摘要： Sulfidic minerals containing metal values such as copper, silver, nickel, cobalt, molybdenum, zinc, iron, or mixtures thereof are oxidized with nitrogen dioxide to enable the metal values to be solubilized in an aqueous acidic leach liquor. In practicing the invention, the minerals are added to an aqueous acidic leach liquor and a nitrogen dioxide containing gas is sparged through the slurry to oxidize the metal values. During the reaction, the nitrogen dioxide is reduced to nitric oxide. The nitric oxide is oxidized to nitrogen dioxide by oxygen, either in-situ, or in a separate off-gas oxidizer.

摘要： Waste materials containing significant quantities of zinc oxide are mixed with carbon and a sufficient amount of copper to set the overall Zn/Cu weight ratio to a selected value below 0.66. The mixture is loaded into the top of a shaft furnace having a lower region which is heated. Hot gas rising from lower regions of the shaft furnace preheats the mixture as it descends. Rising zinc vapor is prevented from escaping the furnace because it condenses in the relatively cool preheated mixture descending down the furnace. As the mixture descends, it enters a brass production zone where zinc vapor alloys with the copper in the mixture. Further descent brings the mixture to a zinc reduction zone where the temperature is above 950.degree. C and where ZnO is reduced by carbon or carbon monoxide to produce a zinc vapor which rises coutercurrently to the charge. Molten brass and some slag is removed from a brass reservoir which forms in the bottom of the furnace.

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 cyclic process for selective recovery of a metal from a material which contains other metal values in addition to the selected metal, comprises leaching the material with an aqueous solution capable of leaching metal values including the selected metal from the material. The resulting, aqueous solution, containing the selected metal and other metallic contaminants, is dispersed in an organic medium comprising an exchange reagent which is capable of selectively extracting the selected metal from the aqueous solution while rejecting any other metal values in the aqueous solution. The dispersion, comprising the aqueous solution and the organic medium containing the extracted metal, is passed as a flowing stream through a zone in which there are a plurality of spaced, parallel, elongate electrodes. Flow of the dispersion is such that it is distributed uniformly about the electrodes. An alternating current potential is applied to the electrodes to create an A.C. electrical field within the zone sufficient to electrically coalesce the aqueous phase of the flowing dispersion, and the aqueous phase is then separated from the organic phase in a separation zone downstream from the electrodes. The selected metal values are stripped from the organic phase by dispersing the organic phase in an aqueous stripping solution. This dispersion is then resolved into an organic phase and an aqueous phase by flowing the dispersion through a zone as is described above. The selected metal is recovered in essentially pure form from the aqueous phase, and the organic phase can be used in further selective extraction of metal values from aqueous leach solution.

摘要： Improvements are disclosed for a process of the type in which copper metal is produced by contacting an aqueous solution containing copper ions with a quinolic compound to result in the precipitation of copper metal. In this type of process, a quinonic compound is also produced during copper precipitation and it may be reduced to the quinolic compound for reuse in precipitating more copper metal.A two step reduction of copper is disclosed. In a first step, cupric copper is reduced to cuprous copper and in the second step, cuprous copper is reduced to copper metal.The inclusion of selected concentrations of chloride ions in the copper solution is disclosed to increase the rate at which copper is precipitated.The in-situ conversion of the quinolic compound contained in the raffinate to the quinonic compound is also disclosed to reduce extractant losses in the aqueous phase.A solvent system in which the percentage of nonpolar solvent in a mixed organic solvent system is increased is also disclosed to increase the rate of reduction of copper metal.
