The transition to underground mining has enabled 50,000 tpd of conventional crushing, milling and flotation capacity. Copper and magnetite are recovered on behalf of Foskor (a neighbouring mining company) by tollprocessing 20,000 Tpd of marginal ore from stockpiles from the open pit operation.
Compared to other metals, copper is very ductile, meaning that it can be drawn through a tiny hole into very fine wire without breaking. Refining improves the ductility of copper so that extremely fine wires can be drawn. Impurities increase the chance that the wire will break during the drawing conducts electricity
