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.
