摘要： This invention provides a process for obtaining separate solutions of a soluble nickel salt and a soluble cobalt salt from a pregnant aqueous solution comprising a mixture of a cobalt salt and a nickel salt. The nickel and cobalt are extracted together from the pregnant solution by a liquid ion exchange extraction medium and then selectively stripped from the extract. The pregnant aqueous solution can be derived from the leaching of various ores, such as ocean floor nodule ore, or from, e.g., spent electroplating solutions or spent acid pickling liquors, containing nickel and cobalt.

摘要： This invention provides a process for obtaining the metal values from ocean floor nodule ore. The ore comprises primarily oxides of iron and manganese plus nickel, copper and cobalt compounds. The ore is treated with an acidic reagent, e.g., sulfur dioxide in the presence of oxygen, to form the water-soluble sulfates of manganese, nickel, copper and cobalt. The reacted ore is leached with water and the resultant leach solution is treated by liquid ion exchange processes to form separate solutions of each of nickel, copper, cobalt and manganese salts. These salts can then be cathodically reduced to form the respective metals.

摘要： This invention provides a process for separating the halide of cobalt, and optionally nickel, from a pregnant aqueous solution, the aqueous solution also containing a manganese halide. The process comprises initially extracting the cobalt halide and a portion of any manganese halide which is present into an organic extract. The nickel halide is then separately extracted from the solution. The manganese halide is preliminarily preferentially stripped from the organic extract containing cobalt and manganese utilizing an aqueous solution comprising halide ions. The cobalt halide in the extract can then be stripped into an aqueous solution together with the remaining manganese to form a strip solution. The manganese is then preferentially extracted from the strip solution, leaving a manganese-free, substantially pure cobalt solution. Any nickel can be selectively extracted from the manganese remaining in the pregnant solution.

摘要： This invention provides a process for removing metal values from ocean floor nodule ores comprising contacting the nodule ore with a molten bath of an alkali metal halide and/or an alkaline earth metal halide to form the halides of the manganese, copper, cobalt and nickel present in the ore, and separating the thus formed halides from the reaction mixture, as by vaporization. The mixture of halides can then be separated into the individual halides, e.g. by dissolving in water and separating by extraction. Preferably the ore is first dehydrated and the ore can be contacted with a reducing agent to reduce the manganese present to the divalent state.
