Crushing plant flowsheet The mined ore contained 50% minus 10mm material. Given the Crushing Work and Abrasion Indexes, the ore was considered to be not difficult to crush and not overly abrasive The product from the surface mining did not require primary crushing. The ore was loaded into an apron feeder and fed to vibrating screens.

This mine was a leader in the field of surface mining technology with the first in-pit primary crushing facility. This meant that ore was crushed by jaw crushers before taken out of the mine. They also used the first trolley-assist system for haul trucks coming out of the pit. Today the mine has secondary crushing facilities, concentrators and ...
