The crushed ore is transferred to a grinding mill, which contains heavy-duty steel balls or rods. As the mill rotates, the balls or rods crush and grind the ore, resulting in the formation of a fine powder. The purpose of crushing and grinding the gold ore is to liberate the valuable gold particles from the surrounding rock and minerals.

19th century Chilean Ore Mill. The nineteenth century Chilean Ore Mill was used to crush gold bearing ore to aid in gold recovery. It is thought to be the only remaining complete mill with all original working gears in the U.S. This same mill was in operation in Gold Hill, North Carolina from 1840-1900.
The stamp battery is the heart of a stamp mill and the mechanical separation process to break the various components of the ore apart, freeing the gold from its enclosing material. To start, the mined rock enters the mill and passes over a grizzly (like a grate- kit# M1 ) that has bars spaced to allow rocks that the stamp battery can handle to ...

Oxidized ores have been processed by these more straight forward methods. However, as oxidized ore deposits are diminishing in occurrence, refractory ores have risen in importance. Refractory gold ores are typically pyritic, arsenopyritic, and carbonaceous. The gold is present as the metal, and as very fine particles locked in the host minerals.

The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.
Nuggets taken from streams and free gold retrieved by panning, sluicing and dredging could go directly to the smelter.
