摘要： An improved method for processing of nickel-bearing ores, laterite ores, saprolite and limonite ores, oxidic and sulfide ores, metallurgical wastes, and other metal-bearing materials, to recover the valuable minerals contained therein, comprising comminuting ore to a desired size; leaching the ore at about 70C to 130C for about 30 minutes to 4 hours with nitric acid, raising the temperature of the solution to form a liquid/solid residue in which nickel, cobalt and magnesium values are in solution, and iron, manganese, and aluminum are solid residues in oxide form; conducting a liquid-solid separation and removing the solids; and recovering the nickel, cobalt, and manganese from the liquid-metal concentrate. The leachate is recovered and the nitric acid from the leachate is recycled.

摘要： A process is disclosed for separation and recovery of vanadium, molybdenum, iron, tungsten, cobalt and nickel from alumina-based materials, mattes, ores, manufacturing by-products and waste. These elements are oxidized. The oxides are reacted with gaseous HCI to form volatile chloride- bearing compounds that subsequently sublimate. The volatile compounds are condensed in a downward-stepped thermal gradient that allows collection of moderate to high purity compounds of individual elements with exception of a nickel-cobalt co-condensate. Nickel is separated from cobalt by precipitation of nickel chloride from concentrated HCI pressurized with gaseous HCI.

摘要： An improved process for the extraction of a metal from an aqueous ammoniacal solution comprising: (i) contacting the aqueous ammoniacal solution with an extraction reagent comprised of a water insoluble extractant for the metal, to provide an organic phase, now containing metal values, and an aqueous phase from which metal values have been extracted; (ii) contacting the organic phase with an aqueous stripping solution to provide an aqueous strip phase, now containing metal values, and an organic phase from which metal values have been stripped; and (iii) recovering the metal values from the aqueous stripping solution; the improvement wherein (a) the extraction reagent contains an ammonia antagonist having only hydrogen bond acceptor properties; (b) the stripping solution is an aqueous highly acidic solution; and (c) the organic phase is washed with a weakly acidic aqueous solution prior to stripping with the highly acidic aqueous stripping solution. The extractant is preferably an oxime extractant, either a ketoxime or an aldoxime. The preferred hydrocarbon solvent is kerosene and the preferred antagonist is 2,2,4-trimethylpentane-1,3-diol diisobutyrate.

摘要： Le procédé décrit sert à la séparation et à l'extraction de nickel à partir d'une solution de carbonate d'ammonium ammoniacale contenant des ions de nickel II et des ions de cobalt III par extraction liquide-liquide. Des solutions de carbonate d'ammonium ammoniacales sont les phases aqueuses utilisées dans le procédé. Celui-ci consiste: (a) à oxyder la majorité des amines de cobalt II dans le liquide ammoniacal pour les transformer en cobalt III; (b) à extraire le nickel de la solution ammoniacale à l'aide d'un réactif organique, lequel peut aussi contenir un réactif de modification approprié, afin de former une phase organique chargée de nickel et une phase de carbonate d'ammonium ammoniacale contenant du cobalt; (c) à dépouiller la phase organique chargée de nickel, ce qui se caractérise par la mise en contact de la phase organique avec une solution de carbonate d'ammonium ammoniacale, afin de former une solution de dépouillage aqueuse chargée de nickel.

摘要： A monoalkyl alkylphosphonate represented by the formula (I), (wherein R1 and R2 each represents an alkyl group, with R1 containing 4 carbon atoms and R2 containing 8 carbon atoms) is used as an extractant for separating and recovering nickel and cobalt from Ni- and Co-containing scraps, waste catalysts, etc. according to solvent extraction. The use of this extractant enables one to conduct smooth pumping or the like even when cobalt is contained in a high content since the kinematic viscosity is not increased so much, and to easily obtain highly pure nickel and cobalt due to its extremely high extractive separation coefficient of nickel and cobalt.
