2020-1-31  Aluminum is first mined from an open pit mine for the ore of metal which is called bauxite. Because aluminum is a highly reactive, it tends to mix with other metals, the bauxite ore is heated at around 2000°C. This separates all the metals and turns then into liquid and aluminum is extracted from this mixture which is called aluminum oxide.
