Before mining can commence the land needs to be cleared of timber and vegetation. Milling: Several meters of rock and clay are removed by blasting, drilling, and bulldozers. The bauxite is then transported to the crushing and washing area, reducing the particle size and increasing the available surface area for the digestion stage.
