Mining And Mineral Processing

Once a suitably sized deposit of a mineral has been found, mining can begin In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand Mining is largely divided into surface and underground mining Minerals are often found in river beds, beach sands and other sandy areas.

Extraction Process of Aluminium from Bauxite Ore

Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present process Bauxite is the general name given to the hydrated oxides of aluminum.

Introduction to Mineral Processing

In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer Sulfide and non-sulfide minerals as well as native metals are recovered by froth flotation.
