Geology What is a Mineral Deposit? — Mining Focus

An ore deposit is a mineral deposit which has high enough grades of metal that makes it economic to mine Essentially this means that per tonne of rock containing the desired minerals the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rock Get Price
