Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done.

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.

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.
