    Mining. Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.

    The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

    Mining. In Australia, nearly 80% of coal is produced from open-cut mines, in contrast to the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource.
