Ore head grade (i.e. copper and valuable by-product content) as this determines the mass or ore that must be moved and processed to recover a given unit of copper. The mining method and geometry, especially for open pits as this determines the quantity of waste that must be moved (determined by stripping ratio), and the length and elevation of ore and waste movement.

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of
