摘　　要：Nickel has found increasing application in electronic,automobile manufacturing,plating,and metal industries and so on.Producing high quality metal powders to satisfy increasing demand for advanced materials is of very high importance.There are a few numbers of standard powder production techniques.An acidic leaching has been applied in present research.Sulfuric acid has been used to leach nickel wastes of plating industry.To produce nickel oxide powder furnaces with no protecting atmosphere and to produce pure nickel powder,tube furnace with hydrogen atmosphere has been applied.Variables performed in the research are time,density of sulfuric acid,and amount of hydrogen peroxide.To analyze powders produced,EDS element analysis and to determine size of powder particles,SEM has been applied.It was shown by the results that the highest amount of nickel dissolution in sulfuric acid(98%)has taken place during one hour and there is a direct relationship between hydrogen peroxide amount and nickel dissolution in sulfuric acid.
