对黄金冶炼厂在焙砂酸浸系统中生成的结晶物进行了化学定性分析 ,确定了结晶物的主要成分为钙、镁的水合硫酸盐 ,二氧化硅 ,氧化铁等 ;并根据盐类结晶理论探讨了结晶物的形成机理 ,指出钙、镁硫酸盐类的过饱和浓度较高是形成此类结晶物的首要因素 ;评价了防止、消除结晶物的现行几种方法 Chemical qualitative analysis of the crystals produced in the gold smelting plant in the acid leaching system of the romanizer confirmed that the main components of the crystal were calcium sulfate hydrates, magnesium sulfate, silica, iron oxide and the like; and according to the salt crystallization The formation mechanism of the crystal was discussed theoretically. It is pointed out that the high supersaturation concentration of calcium and magnesium sulfate is the primary factor for the formation of such a crystal. The current methods to prevent and eliminate the crystal are evaluated
