Scrapers and small excavators are used to remove the remaining overburden and expose the caprock. Depending on the depth of the caprock, it can be broken by blasting, or simply removed with scrapers and excavators. The bauxite is then mined using excavators or loaders to load the bauxite onto haul trucks and transported to the crusher.
