铝土矿生物浸出液中有机酸的回收方法研究

Development of organic acid recycling methods from bauxite bioleaching solution

使用微生物发酵液可以浸出铝土矿中的有价元素,起作用的主要是发酵液中的生物酸即有机酸,而浸出后残余有机酸的回收是铝土矿微生物浸出工艺中的一个重要环节。本文综述了铝土矿微生物浸出液中有机酸的回收,指出现阶段回收浸出液中有机酸常用方法的优缺点,为以后的发展提供一点建议。

Microbial fermentative liquid containing organic acid was used to extract valuable elements from bauxite. After leaching, it was an important procedure to recycle the remainder organic acid in leaching solution for bauxite leaching process. In this paper the researching status about organic acid recycling from bauxite bioleaching solution were summarized and normal processes for recycling organic acid from bauxite bioleaching solution at present and their advantages and disadvantages were described, then researching direction in the future was pointed out.
