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

Gold in Quartz - February 2016 (Vol. 85, No. 06) - ICMJ's

In many gold ores, the majority of the gold is located in cracks and the space between the quartz crystals. This happens because gold is often deposited in the last phases of vein formation. The result is that the first crushing step will yield the most gold, with each pass after that yielding less. Each step is much more and yields
