Bauxite – Mars Mining Resources India

Methods of Bauxite Mining. There are two main methods for mining bauxite – open-pit mining and underground mining. Open-pit mining involves digging a massive pit in the ground and removing the layers of bauxite ore using heavy machinery. On the other hand, underground mining involves tunneling deep into the earth to access bauxite deposits. ...
