The gold milling process consisted of three general steps: (1) Sorting the ore by size (2) Crushing the rock (3) Extracting the gold. The rock fragments were sorted according to size in a grizzly, which was device consisting of a series of spaced bars, rails, or pipes, above a forward moving conveyer belt to a crusher machine.

Gold is found in two ways; as hard rock sources within ore, and as placer deposits where the gold has separated from its host material. Most prospectors today prefer placer mining because they can use simple tools like gold pans and sluice boxes, but don't overlook hard rock sources either!
