grinding mill iron-poor magnetization plant manager

Aug 01, 2020 The content of magnetic iron, iron carbonate, iron sulfide, and iron silicate was relatively low; therefore, the main recoverable element of iron in this sample was hematite. It is clear from Table 3 that manganese primarily existed in the form of braunite and pyrolusite, with the distribution rates of 47.95% and 44.64%, respectively.

  • Redox synthesis of magnetite powder under mixing grinding

    Redox synthesis of magnetite powder under mixing grinding

    Aug 31, 2004 Redox synthesis of magnetite powder from metallic iron and FeO(OH) under mixing-grinding with the assistance of H 2 O 2 as an oxidizing reagent has been proposed. Deformability of the metal–oxide system induces the kneading of am-FeO(OH) into metallic iron to activate, while the iron is oxidized to Fe(OH) 2 and/or FeO by H 2 O 2 contained in the grinding liquid (acetone).
