摘要

本文介绍了用碱性试剂(蛇纹石、菱镁矿和氧化钙)从硫酸盐溶液中析出锌的结果。x射线衍射、显微形貌分析和热力学模拟表明，在偏蛇形碱为试剂的实验中，形成了稳定的亚稳硅酸盐含锌相。当氧化钙作为反应物时，锌精矿析出。

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.
