A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
While gold deposits can be things besides quartz veins, gold is certainly found in the quartz of veins cutting through various types of rocks. Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling cracks and openings in the vein material.

Mills from 4 to 6 ft. in diameter and from 16 to 22 ft. long are usually termed tube mills. This was the first type of rotary mill for metallurgical purposes. Because of the necessity of completing the grind during one passage (open circuit) of the ore through the mill, it was built with a large lengthdiameter ratio.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The Quartz Mill AKA Chilean Mill is one of the more popular types of the original Chilean mill. Still used for certain grinding problems, this mill employs the convexconcave principle of crushing ores, resulting in a product surprisingly low in slime content and which has its particles, such as sulfides and gold, well polished and free of recovery retarding tarnish.

Another thing to consider, is that the gold within many ores is microscopic particles, which require advanced methods to extract, such as through cyanide leaching. Extracting gold from this type of ore is feasible for multimillion dollar mining companies, but almost impossible for the average person to do.

Removing the goldbearing 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 ...
Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
