What are the different stages of mining?

Prospecting, the first stage in the utilization of a mineral deposit is the search for ores or other valuable minerals (coal or nonmetallics) Because mineral deposits may be located either at or below the surface of the earth, both direct and indirect prospecting techniques are employed...
