Recovery of copper and zinc from scrap leaded brass

Abstract

It has been observed that the size of the particulates in samples used in the analysis of minerals affect the intensity of X-ray fluorescence. In this investigation, the heterogeneity effect due to variation in particle size was examined for binary mixtures of silica and calcium carbonate, in size was examined for binary mixtures of silica and calcium carbonate, in sizes ranging from 20 to 250 microns. It was observed as usual that the increase in particle size of a constituent in a mixture of fixed composition results in the decrease in the X-ray fluorescence intensity of the element under investigation. A correlative polynomial was, therefore, derived between the particle size and X-ray fluorescence intensity of the constituent in the mixture of binary oxides which has been observed to simplify the process of analysis.
