Two types of coal are mined in Australia, depending on the region: high-quality bituminous coal (black coal) and lower-quality lignite (brown coal). Total production of bituminous coal in Australia in the financial year 2010-11 was 405 million tonnes, down from 471 Mt. Australia is the fourth largest producer of coal, and by proportion exported, Australia is the largest exporter of coal in the world, with most of the exports going to Japan. This drop was largely as a result of the Queensland floods of January 2011 where production in that State fell by some 30%. in 2009-10.
The first step in copper ore extraction operation is crushing and grinding, where the rock is crushed to produce small particles (.Copper ore can be mined by both open pit quarrying and underground mining methods according to ore deposit characteristics.
Following crushed by jaw crusher, the gold ore resources can be decreased to smaller sizes. Frequently used grinding mills are ball mill, vertical curler mill, ruthless suspension grinding mill, MTM medium speed trapezium mill and SCM series super thin mill. Secondary crushing: following reaching specific size, the kinds of components could possibly be provided to grinding mills for more grinding.Crushing is usually split into 3 phases, namely, primary crushing, secondary crushing and fine crushing. Impact crusher is normally used soon after jaw crusher. In the primary crushing, individuals typically use a jaw crusher or possibly a impact crusher.
