| description | This research include extraction of nickel metal from residual of fired heavy oilin electric power station, the residual were pretreatment by grinding and sieving,the nickel concentrated by particle size.Magnetic separation was also performed in order to get rid of iron that was inheavy oil residual in the form of magnetite, and the results show the ability ofseparating 86% of iron.Vanadium was recovered from the residual by alkaline leaching method usingsodium hydroxide solution and this step resulted in the leaching 98.63% ofvanadium, also increasing nickel concentration to 16.27%.Subsequently extraction of nickel from the residual was studied using thehydrometallurgy method. The leaching of nickel from the residues was carriedout using sulfuric acid and the result obtained show the possibility of obtainingthe highest leaching ratio at acid concentration 3 molarity, temperature 100oC,time of leaching 90 minutes and solid /liquid ratio 5 gm/l.In order to recover H2SO4 from the pregnant liquid, ion exchange process wasemployed using strong anion exchanger and the concentration of nickel increasesin the liquid resulting from ion exchange process by evaporation |
