Like most mining operations, the aluminum mining process begins with prospecting. Geologists start by taking samples from the earth and testing them for bauxite, the ore in which aluminum is usually found. Since bauxite typically settles in layers of earth that stretch for several miles, even small traces of it could indicate that a major ...
