Metal prices as a function of ore grade

open cut and block caving methods. However, grade cannot be the only determinant of costs. In the case of certain common oxide ores such as hematite and bauxite the mining costs are small compared with costs of separating the useful metal from the mineral. Costs might also depend on the difficulty of finding orebodies.
