Stages of Mining. There are generally 6 steps to perform mining and these are as follows: Stage 1. Surveying/Prospecting. The initial stage in the process will demand skilled workers or even AI to use geological knowledge to be able to identify locations where a particular ore could be found. In this process, there are two known methods that ...

costs associated with bringing a mine into production through the four. stages of prospecting, exploration, development, and exploitation is called. the direct mining cost. If calculated on a gross basis, it is a total cost; if on a. unit ($/ton, or $/tonne) basis, it is a unit cost. In addition, indirect mining cost.

These five stages of a mining project tie in directly with a concept known as the "mining life cycle." It's also referred to as the "Lassonde Curve." Pierre Lassonde is the mining legend who co-founded Franco-Nevada, the world's first gold royalty company. Some three decades ago, he created this now well-known chart.

1. Locate Potential Deposits. One of the first steps of mineral exploration is to locate areas that are likely to yield mineral deposits. Since mineral deposits tend to form in clusters, prospective areas may be near other areas of known mineralization or near existing mine sites. They may also be identified with aeromagnetic surveys, satellite ...
