The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Potential cost savings measures. This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G A). In addition, G A costs were found to be consistently lower than both Milling and Mining costs.
