2016-2-10 · Gold mining is the process of mining gold ores from the ground up till the stage where pure gold is extracted (Richiewiki, 2010). The gold ores are usually big and have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted from them. The ore usually has to pass various crushing stages, each reducing the ore to a certain size. Crushing plant layout is of vital importance. Gold-containing rocks are crushed for several reasons. Crushing reduces the physical size of large rocks, exposing more surface area of rock, thus exposing any gold that may be in the rock and increasing the probability of obtaining the gold from the rock by gravity concentration or by leaching with cyanide. There may be several sizes and shapes of gold grains in the rock--round, flat, coarse or tiny. Because of this, several stages of crushing or grinding can be required (WebElements, 2015). Secondary factors to consider when crushing are the desired size of the crushed material and quantity of material to be crushed
