    Abstract:

    The technology of preparation of ferric oxide from zinc hydrometallurgy high iron slag by hydrothermal method, which realized the separation of zinc-iron and utilization of iron associated effectively, was proposed and investigated. The effects of iron precipitation ratio, the constitution and morphology of the product were studied with respect to variables such as temperature, reaction time, pH values of the solution as well as stirring speed. The experimental results showed that the influence was obvious, in which the reaction temperature was the most important factor. The iron precipitation ratio could reach 95%, and the spherical nanometer hematite could be obtained under the optimum conditions, it were determined as follows, when the stirring rate was fixed at 800r/min, oxygen pressure was fixed at 2.0MPa: the minimum reaction temperature is 180, pH1.0, 1h.
    Key words: iron oxide red, hydrothermal method, iron precipitation ratio, morphology.
