摘要： An aqueous cobalt chloride solution purification method, in which impurities can be efficiently removed from a cobalt salt solution, includes bringing metallic nickel into contact with an aqueous solution containing cobalt chloride to remove an impurity by a substitution reaction, in which the pH of the aqueous solution containing cobalt chloride is adjusted to not less than 1.5 and not more than 2.5. Since the pH of the aqueous solution containing cobalt chloride is adjusted to not less than 1.5 and not more than 2.5, a passive film on a surface of the metallic nickel can be effectively removed, and the metallic nickel comes in contact with the aqueous solution containing cobalt chloride, so that an impurity more noble than the metallic nickel can be precipitated by the substitution reaction. The metallic nickel is only brought into contact with the aqueous solution containing cobalt chloride, and the impurity can be easily removed.

摘要： A method by which the amount of nickel contained in an alloy having a composition represented by Sn—X—Ni can be regulated. The method of nickel concentration regulation comprises adding phosphorus to Sn—X—Ni in a molten state (wherein X is one or more elements selected from the group consisting of Ag, Zn, Cu, Bi, Au, Ti, Ge, Ga, Si, and Ce), holding the mixture at 250-400° C., and removing the resultant dross floating on the surface of the liquid phase and containing a P—Ni compound and a P—Sn—Ni compound. An example of X is copper, and the content thereof may be 0.3-5 wt %. The phosphorus may be added in the state of a Sn—P alloy. The upper limit of the amount of the phosphorus to be added may be about half the nickel amount in terms of atomic amount.

摘要： A nickel deposition includes a reactor system for producing nickel carbonyl and storing same as a liquid, a plating system where the liquid carbonyl is vaporized and applied to product and deposited thereon, with carbon monoxide being released in the process, a reclaim system for cooling the gases received from the plating system and cooling them to a temperature just above its freezing point to condense out and recover the liquid carbonyl, said reclaim system including a reclaim condenser, and a vapor recovery system including a gas receiver for receiving vapors from the reclaim system. The vapor recovery system includes a first stage compressor operatively connected to the first stage receiver for pressurizing the vapor to about 25 PSIG, and a first stage condenser operatively connected to the first stage compressor for cooling the vapors. A conduit communicates the vapor recovery system to the reactor system for forwarding the cooled vapors to a recycle pump receiver in the reactor system. A compressor is provided in the reactor system for compressing the gases from the recycle pump receiver to about 65 PSIG. The nickel deposition system recovers and recycles substantially all of the nickel carbonyl and the requirements for carbon monoxide are substantially reduced.

摘要： A process for the removal of harmful impurities, particularly arsenic, antimony, bismuth and lead, from metallurgical sulphide melts, in which the sulphide melt is sulphurated before conversion, during the slag-blowing stage or after it before the blister-blowing stage, and the melt is refined with nitrogen or other inert gas during sulphuration and possibly after it, so that the amount of sulphur supplied to the sulphide melt is at least 10% in excess of the stoichiometric sulphur amount as calculated from the sulphur requirement of the principal components of the melt.

摘要： A novel process for recovering nickel metal from aqueous ammoniacal nickel solutions such as leach liquors at or close to ambient temperatures and pressures. The process comprises contacting the nickel solution with carbonyl ferrate ions such as HFe(CO).sub.4.sup.- or Fe(CO).sub.4.sup.-- in the presence of carbon monoxide to produce nickel carbonyl. The nickel carbonyl is collected as a gas, concentrated, and decomposed to produce nickel metal and carbon monoxide. The carbonyl ferrate ions may conveniently be produced by subjecting an iron pentacarbonyl solution to an aqueous alkaline solution containing potassium hydroxide or the like. The nickel depleted ammoniacal liquor is purged of iron resulting from the nickel carbonylation treatment by oxidizing the ferrous values to iron oxide and may thereafter be recycled to solubilize additional nickel values. The iron oxide in turn may be reduced to iron pentacarbonyl and treated with an aqueous alkaline solution for reuse in carbonylation of additional nickel values.

摘要： A novel process for extracting, concentrating, and isolating nickel and cobalt from aqueous solution thereof. A cobalt and/or nickel bearing solution is contacted with an extractant comprising a substantially water immiscible organic solvent containing solubilized mercaptide anion to form water insoluble cobalt and nickel mercaptides in the organic phase. The organic phase is then separated from the raffinate and contacted with an alkaline solution and carbon monoxide to produce nickel and cobalt carbonyl compounds. Typically, the nickel carbonyl produced is gaseous Ni(CO).sub.4 which may be easily isolated by known methods from other components in the off-gas stream. Pure nickel metal is then obtained from the nickel tetracarbonyl by known methods. The cobalt carbonyl compound produced is typically water soluble carbonyl cobaltate ion, Co(CO).sub.4.sup.-, which may be oxidized to form water insoluble cobalt carbonyl compounds. The stripped extractant, the cobalt and nickel-free raffinate, and the carbon monoxide from the decomposition of carbonyl may be recycled.
