Abstract
In this paper, based on the analysis of oxidized ore from a mine in Guangxi, the composition and content of elements and minerals, and the chemical composition of main minerals were studied by mineral liberation analyser method. The results show that the ore is a zinc-rich limonite, the content of the main mineral limonite is 47%, the majority of limonite is monomer, a few limonite is associated with clay, dolomite and so on, and cemented by clay. Zinc occurs mainly in the form of minerals such as smithsonite and hemimorphite, while a large amount of zinc occurs in limonite in the form of dispersion. The content of smithsonite is 8.73%, most of them are crust-like, colloidal ring-like, and are associated with limonite. The content of hemimorphite is 3%, most of them are single particle. This study will lay a mineralogical foundation for the follow-up development and utilization of this type of ore.
