FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgy, particularly to method of nickel extraction from nickel-containing materials. Method includes separation of nickel-containing materials by fractions, its leaching and processing of productive solution. Additionally after factional separation fraction +2.0 is directed to heap leaching. Received productive solution and fraction +(0.05-0.15) - (-2.0) is directed to agitation leaching.
EFFECT: increasing of nickel extraction ratio.
