摘要： After optional preliminary treatment, solid wastes are processed in accordance with the flowsheet FIG. 1: first, Cu is leached selectively with a leaching solution containing Cu(II) ammine as a leachant according to the autooxidation or the autocatalytic action which proceeds depending on the equations: ##STR1## and the Cu(II) ammine concentrated in the leaching solution is extracted with a solvent Lix-54; thereafter, Cu.sup.2+ is stripped so that it moves into a Cu electrolyte and Cu electrowinning is performed to have metallic Cu deposited at the cathode, with the total process being carried out in a closed circuit. By this process, copper and other nonferrous metals can be selectively recovered from motor scrap and shredded solid wastes such as abandoned automobiles and home electric appliances in a simple and economical manner.

摘要： Uranium and other base metals are leached from their ores with aqueous solutions containing bicarbonate ions that have been generated or reconstituted by converting other non-bicarbonate anions into bicarbonate ions. The conversion is most conveniently effected by contacting solutions containing SO.sub.4.sup.= and Cl.sup.- ions with a basic anion exchange resin so that the SO.sub.4.sup.= and Cl.sup.- ions are converted into or exchanged for HCO.sub.3.sup.- ions. CO.sub.2 may be dissolved in the solution so it is present during the exchange. The resin is preferably in bicarbonate form prior to contact and CO.sub.2 partial pressure is adjusted so that the resin is not fouled by depositing metal precipitates. In-situ uranium mining is conducted by circulating such solutions through the ore deposit. Oxidizing agents are included in the injected lixiviant. The leaching strength of the circulating bicarbonate lixiviant is maintained by converting the anions generated during leaching or above-ground recovery processes into HCO.sub.3.sup.- ions. The resin may conveniently be eluted and reformed intermittently.
摘要翻译：铀和其他贱金属从含有通过将其他非碳酸氢根阴离子转化为碳酸氢根离子产生或重构的碳酸氢根离子的水溶液从其矿石中浸出。通过使含有SO 4 =和Cl-离子的溶液与碱性阴离子交换树脂接触使得SO 4 =和Cl - 离子转化为或替换为HCO 3 - 离子，转化最方便。二氧化碳可能会溶解在溶液中，以便在交换过程中存在。树脂优选在接触之前为碳酸氢盐形式，并且调节CO 2分压，使得树脂不会通过沉积金属沉淀物而被污染。通过使这种溶液循环通过矿床进行原位铀矿开采。注射剂中包含氧化剂。通过将浸出过程中产生的阴离子或地上回收过程转化成HCO3-离子来维持循环碳酸氢盐浸液的浸出强度。树脂可以方便地洗脱并间歇地重整。

摘要： The present invention concerns a process for smelting nickel which comprises treating nickel-containing material with a reducing gas to reduce the nickel component contained in the nickel-containing material and thereby produce metallic nickel; soaking the thus-obtained material in an ammoniacal aqueous ammonium salt solution and treating it with oxygen or an oxygen-containing gas in the presence of free ammonia in order to produce an aqueous nickel ammine salt solution; treating coal with the thus-produced aqueous nickel ammine salt solution so that the coal becomes impregnated with the nickel ammine salt; separating and recovering ammonia from the thus-treated coal; gasifying catalytically the coal containing the nickel compound in the presence of a gasifying agent, thereby producing a reducing gas and a solid residue; employing part of the thus-produced reducing gas for the treatment of the nickel-containing material; and separating and recovering metallic nickel from the solid residue.

摘要： A process in which copper, nickel, cobalt and molybdenum are recovered by reducing comminuted raw manganese nodules with an aqueous solution containing cuprous ions. An improvement is disclosed in which copper is oxidized to provide a starting solution of cuprous ions for the process. In one important embodiment of the invention wet copper cement is added to a solution of carbon dioxide and ammonia and ground manganese nodules are then added to the mixture. As a result, a starting solution containing cuprous ions is produced. A major advantage gained from utilizing manganese nodules as an oxidizing agent is that the manganese nodule is itself reduced and its metal values are added to the reaction solution.

摘要： Process in which manganese nodules are treated to enable metal values to be recovered. Manganese ore nodules are treated in a two-stage fluid bed process to produce a leachable product. In the first stage, dried nodules are calcined using direct fuel injection under a neutral or slightly oxidizing atmosphere to remove about one-half of the oxygen content. Subsequently, in the second stage, the calcined nodules are reduced with synthesis gas to render the metal values leachable. The metal values such as copper and nickel are leached from the reduced nodules with an ammonia-ammonium carbonate leach solution.

摘要： Ammonium hydroxide is added to a mixture of high-temperature, high-pressure geothermal steam and brine to raise the pH of the brine to between 6.0 and 7.0 and precipitate out a gelatinous sludge of aluminum and iron hydroxides. The hydroxide sludge is suspended in the brine and sweeps out enough dissolved silica so that the temperature and pressure of the brine can be reduced with little, if any, formation of silica scale. Various metals and ammonium hydroxide may then be recovered from the brine, the ammonium hydroxide being recycled in the process.

摘要： The process is disclosed for recovering elemental nickel from an impure aqueous ammoniacal ammonium carbonate liquor containing, in addition to nickel, one or more impurities such as sulphur, chlorine, cobalt, magnesium, manganese, iron, zinc and copper. According to the process, the composition of the liquor is first adjusted to contain at least 1.5 moles sulphur in the form of dissolved ammonium sulphate per mole of contained nickel. The resulting liquor is then heated to drive off ammonia and carbon dioxide to produce a nickel diammine sulphate solution from which elemental nickel is recovered. At least one mole of ammonium sulphate is formed in the solution per mole of recovered nickel and the sulphate containing solution is recycled, at least in part, to make up the sulphur requirements of the first step.
