FIELD: metallurgy.
SUBSTANCE: invention concerns metallurgy field. Particularly it concerns receiving technique of nickel and can be used at treatment of efficient solutions of sulfuric acid leaching of nickel. Treatment technique of sulfuric acid nickel-bearing solutions includes its rectification from ferric iron by solution neutralisation till pH=5 and extraction from it nickel. At that neutralisation till achieving pH=4 is implemented by alkali metal hydrate, and further neutralization from pH=4 till pH= 5 - by aqua ammonia.
EFFECT: increasing of nickel extraction from efficient solution of sulfuric acid leaching at its purification from ferric iron.
