Physical and chemical modeling of the ZnSO4-CaO(MgO)-SIO2-H2O system

The paper presents the results of zinc precipitation from sulfate solutions with alkaline reagents (serpentinite magnesite and calcium oxide). X-ray diffraction, micromorphological analysis, and thermodynamic modeling revealed the formation of stable metastable silicate zinc-containing phase in the experiment with the use metaserpentine as a reagent. When calcium oxide is used as a reactant, zincite precipitated.
