Processing costs
Chemical Form of the Mineral
- cost of extracting a metal depends upon other elements with which it is combined
- the more energy needed to break the bonds the more expensive it will be to extract the metal
Purity
- financial cost of extracting metal from rock increases rapidly as purity of ore decreases
- to produce 1 tonne of metal, greater quantity of rock must be extracted and more energy is required for the chemiccal seperation of the metal from its ore
- the cut-off ore grade is the lowest ore purity that can be exploited econmically
- deposits that are below cut-off ore grade are not included in reserves also changesalthough…
