Falling copper ore content therefore has an impact on the costs for energy and consumables. Lower ore content primarily demands a higher runofmine (ROM) in the mining operations, to obtain the same metal yields. This especially affects the volumes processed in the mill circuits. Another important influence emerges when finer grinding is required.

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.
