摘要: 物理选矿法难以处理微细嵌布且杂质呈类质同象的菱镁矿,造成资源的浪费。为此,概述了菱镁矿及其尾矿化学法除杂技术现状,包括应用广泛的铵盐法、酸浸法,基于特定反应的碳化法,工艺简洁环保的水化法,提纯效率高的氯化焙烧法,指出低品位菱镁矿除杂应聚焦技术研发、绿色浸取剂研发及全产业链模式构建的发展方向。

关键词: 菱镁矿, 尾矿, 铵盐法, 碳化法, 酸浸法, 水化法, 氯化焙烧法

Abstract: It is difficult for physical mineral processing to treat magnesite with fine dissemination and isomorphic impurities,resulting in resource waste.Therefore,the present situation of chemical impurity removal technologies for magnesite and its tailings was summarized,including the widely used ammonium salt method and acid leaching method,the carbonization method based on specific reactions,the simple and environmentally friendly hydration method,and the chlorination roasting method with high purification efficiency.It was pointed out that the impurity removal of low grade magnesite should focus on the research and development of technologies and green leaching agents as well as the construction of a full industrial chain model.

Key words: magnesite, tailings, ammonium salt method, carbonization method, acid leaching method, hydration method, chlorination roasting method
