引言 “有效氧化铝”一般可以定义为铝土矿总氧化铝中通过可行的工业过程能够提取的部分。可以认为,它是确定铝土矿质量的一个最重要的因素。因此,对潜在矿石中有效氧化铝的估算,是铝土矿勘探的一个必要组成部分。测定有效氧化铝的最佳方法是在实验室模拟工厂条件,通常是在钢制高压釜中用氢氧化钠溶液进行浸取。但这种方法费时,而且需要专门设备。 Introduction “Effective alumina” can generally be defined as the portion of bauxite total alumina that can be extracted by a viable industrial process. It can be considered as one of the most important factors in determining the quality of bauxite. Therefore, the estimation of available alumina in potential ores is an essential part of bauxite exploration. The best way to determine the effective alumina is to simulate the factory conditions in the laboratory, usually with sodium hydroxide solution in a steel autoclave. However, this method is time-consuming and requires specialized equipment.
