Method for preparing pigment of zinc ferrite

The method of producing an iron-zinc pigment, a zinc oxide containing minerals and ferrous sulfate as raw materials, 6 ~ 40wt% of hot alkali extraction, purification zincate obtained, was added in 8 ~ 25wt% ferrous sulfate solution zincate solution, maintaining the temperature of the reaction liquid 25 ℃ ~ 60 ℃, zinc salt and ferrous sulfate under oxidative conditions were precipitated α-FeOOH, and Zn (OH) 2 , filtered, washed , dried, calcined to form a zinc ferrite pigment. The method used in a wide source of raw materials, low cost, low production costs.
