Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.

Finally, in 1824, the first bits of gold were discovered. This led to a large surge in the Aruba mining industry, and in 1825 the Bushiribana Gold Mill was constructed to help process the raw ore from Ceru Plat and other mining operations. At one point in its relatively short history, it was producing over one million pounds of gold each year.
