Estimation of Cleaning Efficiency of Clay Removal from Bauxite

The cleaning efficiency of the washing process can be characterized by determination of the amount of silica (clay) agglomerates removed from bauxite surfaces. A semi-empirical model has been developed in which the mass and composition of the washed products and tailings streams can be easily estimated. The model developed is a function of

Mining and Refining Process

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.
