Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. Before mining can commence the land needs to be cleared of timber and vegetation.
Bauxite mining has five steps: Step 1: Preparation of Mining Area . Pre-Mining Surveys are conducted in all new mining areas, to provide information on flora and fauna, to map the extent of any disease, such as dieback, and to identify any significant cultural heritage sites. If rare or protected species or significant sites are present, they ...
