| 摘 要： | 随着世界对锌的需求量的增加,碱法浸出低品位氧化锌矿因其显著的优点（浸出率达90%以上、环境污染小等）而成为国内外研究的热点。本文主要介绍了低品位氧化锌矿氢氧化钠浸出体系的动力学和热力学过程,氨浸体系中氯铵、碳铵、硫氨浸出的国内外各研究单位的最近研究成果,并对碱浸过程中矿石活化、闪锌矿难溶解两类问题进行了讨论。

| Abstract: | With the increasing demand of zinc of the world,the alkaline leaching of zinc in for low grade zinc oxide ore becomes a research hot topic at home and abroad due to its obvious advantages such as high leach rate（90%） and less environmental pollution.This paper mainly introduces the kinetic and thermodynamic process of the leaching of low grade zinc oxide ore in the sodium hydroxide solution,recent research results concerning ammonia leaching system such as ammonium chloride,ammonium bicarbonate and sulfur ammonia.Topics about ore activation and insolubility of zinc blende are discussed as well. |
