Producing High Purity Nickel Metal Powder from Nickel Wastes through Acidic Leaching by Sulfuric Acid

Nickel has found increasing application in electronic, automobilemanufacturing, plating, and metal industries so on. Producing highquality powders to satisfy demand for advanced materialsis of very high importance. There are a few numbers standard powderproduction techniques. An acidic leaching been applied presentresearch. Sulfuric acid used leach nickel wastes platingindustry. To produce oxide powder furnaces with no protectingatmosphere pure powder, tube furnace hydrogenatmosphere applied. Variables performed the research aretime, density sulfuric acid, amount hydrogen peroxide. Toanalyze produced, EDS element analysis determine size ofpowder particles, SEM It was shown by results thatthe highest dissolution (98%) takenplace during one hour there is direct relationship between hydrogenperoxide acid.
