The World's Leading Bauxite Producing Countries Australia is the world's leading producer of bauxite, an aluminium ore that is used as the primary source of the metal. A Bauxite mining facility in Queensland, Australia. Note the color of the soil, reflecting the presence of the reddish brown Bauxite in high concentrations here. Bauxite is a softEnvironmental Risks of MiningUnderground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves largescale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.

1.1 PHASES OF A MINING PROJECT Home ELAWAlthough underground mining is a less environmentallydestructive means of gaining access to an ore deposit, it is often more costly and entails greater safety risks than strip mining, including openpit mining. While most largescale mining projects involve openpit mining, many large underground mines are in operation around the world. 1.1.3Bauxite AIMR 2013 Australian Mines AtlasBauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal, although some clays and other materials can be utilised to produce alumina.Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium.
