Gold mining describes the process of extracting ore – metalrich rock – from the earth''s crust. And, as with other minerals, there are a number of geological processes that are involved in forming these ore deposits. Modern gold mining predominantly takes place in areas where there is a significant concentration of goldbearing ore (ore ...
