Abstract
The solid state interactions of CaO and MgO with synthetic and industrial
ZnFe2O4 (in zinc cake) have been studied using chemical, XRD analysis and
M?ssbauer spectroscopy. The exchange reactions in the systems ZnFe2O4 - CaO
and ZnFe2O4 - MgO have been investigated in the range of 850-1200?C and
duration up to 180 min. It has been established that Ca2+ and Mg2+ ions
exchange Zn2+ in ferrite partially and the solubility of zinc in a 7%
sulfuric acid solution increases. The possibilities for utilization of the
obtained results in zinc hydrometallurgy have been discussed.
