Characteristics and migration rules of major elements of the bauxite in Meitan-Fenggang area, northern Guizhou, China

Abstract

The following results were obtained by analyzing the major elementss of bauxite in the Meitan-Fenggang area: 1) There is a correlation between Al, Si, Fe and Ti elements, and Al is negatively correlated with Si and Fe, Al and Ti have positive correlation, Si is negatively correlated with Fe and Ti; 2) Al, Si and Fe have a downward migration trend, and the migration of Si and Fe to the bottom is the key to the formation of high-grade bauxite; 3) The migration of Fe Al, Si is not completely synchronized, but However, the higher the Al content, the stronger the correlation between the samples Al, Si, and Fe.
