    In Situ Mining. A rarely used process of mining material, In Situ or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating In Situ Uranium Mine.
