The Mining Process Waihi Gold

Mining open pit and underground. See more detail on mining. 2. Crushing The primary crushers located at the open pit mine site, receive ore and waste at separate times. They break the larger rocks down to a size suitable for transport on the conveyor belt. The larger particles from this mill are returned to the S.A.G. mill for more

Hazardous Minerals WA DNR

The presence of certain naturally occurring elements, such as arsenic, asbestos, mercury, and uranium can make exposure to the rocks that contain them hazardous. The Washington Geological Survey provides maps and geologic information on minerals related to environmental and public health issues. Much of WGS’s information on hazardous minerals shows locations of historic mines

Milling Technology in the Nineteenth Century ONE

Underground mining demanded a different approach because it retrieved rock rather than loose soil. Milling of underground ore went through several phases including crushing, heating and mixing with water and chemicals, extraction, and retorting. Initially, miners employed the traditional arrastra mill.

Ore processing Waihi Gold

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. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.

Stamp mill Wikipedia

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.
