| 86 | Hydrogen Reduction of Metal Sulphate Solutions for Decreased Silicon in Metal Powder | US15293980 | 2016-10-14 | US20170106450A1 | 2017-04-20 | Fu QIN |
| Process to decrease silicon content of metal powder produced by hydrogen reduction from ammoniacal ammonium sulphate solutions containing metal ammine complexes, wherein metal (Me) is Ni, Co, or Cu. The process controls the precipitation of metal hydroxide, which is found to be an effective scavenger for silicon. Silicon is preferentially removed from metal diammine sulphate-containing solutions by precipitating with a small amount of a metal hydroxide, and then separating the silicon-bearing metal hydroxide precipitate from the solution. This solution, from which the silicon impurity has been removed with the metal hydroxide precipitate, can then be reduced in one or more densification cycles with a reducing gas to produce an elemental metal powder having a decreased silicon content. Alternatively, the solution is reduced to produce a low silicon metal powder seed material for the first of the one or more densification cycles. | ||||||

| Ammonia is used as precursor source of hydrogen fuel in an on-vehicle internal combustion engine. Ammonia is stored as, for example, a ligand in an on-vehicle transition metal composition. Upon demand for hydrogen by the vehicle's engine control system, ammonia is expelled as a gas from some of the composition and the ammonia gas is dissociated into a mixture of hydrogen and nitrogen and delivered as a fuel-containing mixture to the engine. In a preferred embodiment, the hydrogen is used as a supplement to gasoline as a fuel for engine operation. | ||||||

| In the extraction of certain non-ferrous metals from their sulfide ores by a process where these sulfides are converted to water soluble sulfates by roasting, alkali metal carbonate or bicarbonate, especially sodium carbonate, is added to the roaster feed to promote the sulfatization reaction. Ores containing copper, nickel, cobalt or zinc sulfides are concentrated by froth flotation, the concentrate mixed with carbonate or bicarbonate and roasted. The roasted product is mixed with water to separate these metals as soluble sulfates from iron compounds and other solid residue. The sulfate solution is filtered from the solids and the non ferrous metals recovered by precipitation or electrolysis. | ||||||

| A process is provided for purification of nickel sulfate via ammoniacal leaching and pH regulated solvent-extraction, while providing for regeneration of the extractant and the leach solution. The process is especially suited for hydrometallurgical extraction of high purity nickel sulfate from residue resulting in the regeneration of spent electrolyte in the electrorefining of secondary copper. According to the process, the starting material is leached in an ammonia solution of selected pH to solubilize the nickel as polyammine sulfate, followed by extracting the solubilized nickel by pH regulated solvent-extraction. The extractant is then stripped and regenerated with sulfuric acid by first scrubbing in a first pH range to remove ions that are more electropositive than nickel, then stripping with sulfuric acid in a second pH range to remove nickel ions, and then regenerating the extractant by stripping in a third pH range to remove ions that are less electropositive than nickel. Finally, high purity nickel sulfate is crystallized from the nickel-loaded stripping solution. Further, the spent ammonia leach solution is preferably regenerated. | ||||||
