“…Over thirty kinds heavy metals can be recovered from aqueous solutions by EL, including many precious metals and heavy metals [5]. There are many researches about copper recovery by EL [6][7][8][9]. Meanwhile the ED for acidic aqueous solution that contains copper ions has been studied by several workers [10][11][12].…”

“…Also, it was reported that the maximum nickel recovery from some polluting effluents was obtained within a pH interval of 4.66-5.55 at temperatures higher than 50 °C. 26,36 In addition, Njau and Janssen 37 report that the current efficiency goes through a maximum at about a pH of 5 when using a solution containing NiSO 4 and (NH 4 ) 2 SO 4 . Based on the above statements, a pH of 5.5 was chosen for the following tests.…”

“…3,6,7,14,[36][37][38][39][40][41][42][43] On an industrial scale, Ni electrowinning is performed at 60 °C from purified solutions containing chlorides or sulfates. 18 Likewise, the specific case of electrochemical production of nickel powder is carried out in the temperature range from 45 to 70 °C, 19,24,26 being the powders obtained at these temperatures very fine and easy to grind. However, excessively high temperatures, above 70 °C, should be avoided because Ni(II) hydroxide precipitation is favored.…”

An electrochemical reactor based on a modified hydrocyclone with ultrasonic assistance is examined to analyze the continuous production of nickel powder from dilute solutions simulating industrial wastewaters containing nickel. Under operating conditions, nickel deposition takes place under mass-transfer control and the helical flow inside the reactor generates a high mass-transfer coefficient, thus improving the removal of metal ions. The application of ultrasound is crucial for the detachment of the electrodeposited nickel, which allows its recovery as a metal powder. The best result was achieved at a current density of 5368 A m–2 and 60ºC yielding a nickel powder fraction obtained from the spigot of the device higher than 90%. The gravimetric current efficiency and the specific energy consumption were 33.4% and 23.8 kW h kg–1, respectively, for an experiment lasting 13 min. The nickel particles are of high purity and dendritic nature with an average size of 22.9 μm.

“…They came to the conclusion that with this method it is possible to achieve a particle size of less than 5 nm and by increasing the temperature from 20 °C to 80 °C, the particle size will be in the range of 10 nm to 15 nm. Archana and et al [20] conducted a research titled recovery of nickel powder from copper electrolyte by electrolysis. They were able to recover 87% of the nickel, which increased to 99% under certain conditions.…”

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