First of all, introduce the industrial status quo of hydrometallurgy and the harm of calcium and magnesium crystallization in the process of material preparation and its requirements for basic chemistry of solution chemistry and crystallization phase, and then systematically review the progress of fundamental research on solution chemistry and phase chemistry of related systems. Based on the systematic work and literature analysis, the experimental study on the solubility of calcium at high temperature in heavy metal sulfate system can describe the reasonable thermodynamic prediction model of sulfate ion association, the spectroscopic and quantum chemical studies on the structure of sulfate aqueous solution, Determination of water activity at high temperature in aqueous solution is the focus of future research work.These studies will deepen the understanding of the harmful behavior and laws of calcium and magnesium crystallization in the process of heavy metal hydrometallurgy.It is a new technology to avoid the harm of calcium and magnesium crystals cheaply and environmentally Development has laid an important foundation.
