— Stamp mills have wood or metal beams that crush the ore. Each beam is a "stamp" lifted by cams on a horizontal rotating shaft. Stamp mills were often located on a hillside as they relied on gravity. As raw ore descended through the mill, stamps crushed it into smaller pieces of ore which were treated with cyanide or mercury.

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.
Autogenous and Semi-Autogenous Mills. Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media.

Serious backroad navigation with high-clearance skills are required for access Ophir MIll, and once you're …
— b. Autogenous and Semi-Autogenous Mills: In some cases, autogenous (AG) and semi-autogenous (SAG) mills are used for grinding. These mills utilize the ore itself as the grinding media, reducing the need for additional grinding media. AG/SAG mills are typically used for coarse grinding, where large pieces of ore are efficiently broken down.
