FIELD: chemistry.
SUBSTANCE: invention can be used in varnish and paint and other industries. The method of obtaining magnetite involves formation of iron (II) hydroxide with its subsequent oxidation. Iron (II) hydroxide is partially oxidised with a 0.4-6.0 % CuSO4 solution, after which the obtained precipitate is washed using a magnetic field.
EFFECT: invention simplifies the process of producing magnetite, shortens duration of the process and reduces power consumption.
