Coal is mined by two methods surface or 'opencast' mining and underground or 'deep' mining. By Prasetianto Mangkusubroto. The choice of mining method is largelydetermined by the geology of the coal deposit. Underground mining currently accounts for about 60% of world coal production, although in several important coal producing

9 Step Process for Discovering, Mining Refining Gold

Jan 23, 2012In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. It's largely a matter of technology and requires much expertise and elaborate equipment. Mining for gold today can essentially be broken down into 9 steps.

Coal is processed using dense medium separation for the top coal layer (seam 4) as well as the bottom coal layer (seam 2). Crush and screen technology is also used to supply coal to the power station markets. The principal domestic markets for production are the metals and power-generating industries that consume 2,5Mtpa.

The first off-take removes ash, opening up the available separation surface of the spiral and allowing the remaining material to separate more easily. This separates clean coal from less-clean coal. "The low density spiral is essentially a primary and secondary stage on one centre column," Bornman said.
