This setup is for a 50tph rock gold processing plant. The max input feeding stone size is around 200mm and needs to grind at 0.074 (200 mesh) to release the inside gold. The raw materials feed into a vibration feeder. The vibration feeder with a grizzly bar. The grizzly gap with 100mm.

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.

Hard rock gold deposits can be further classified into three sub classes: free milling, sulfide associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm.

The carbon method requires an additional step where the metals are removed from the carbon. The result of both methods is a finely divided black metal powder of gold and silver. The impure mix of gold and silver is often melted and poured into bars before it is shipped. The gold and silver alloy is called a dore.
