Nov 19, 2014· The process of turning ore into gold bars can be complicated, with several stages required to produce per cent investmentgrade assets. However, if you are keen to learn more about how refining works before making your next investment in gold, here is a quick summary by the Perth Mint.
The erosion process of water over time reveals the places in which large gold deposits can be found. Streams that cut through the rocks carry the smaller elements of gold down with them. Because of the malleable nature of gold, it rarely forms into nicely shaped crystals and mostly is found in lumps or irregular masses that filled the cracks and natural faults in the rocks.
