Express method for quantitative determination of the content of alunite in ore and technological samples

Abstract

This article presents the results of an alternative method for determining the amount of alunite in ore and process samples based on X-ray phase analysis. The essence of the technique consists in comparing the magnitude of the most intense peak 2θ *30о (d = 2,971) on the diffractometer of the analyzed sample with those for pre-prepared reference samples. A special advantage of this method, with all its speed and relative cheapness, is the ability to determine the amount of alunite in a sample without special sample preparation, the use of chemical reagents, and so on.
