following the discovery of platinum in the viceroyalty of new granada at the beginning of the century, its use to degrade gold forced the colonial authorities to improve their existing methods of separating and analysing the precious metals. using information from the royal mint of santa de bogot the various ways of separating these metals are now considered, including the little removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. the first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
