As shown in Table 1, the alumina content should be at least 55% or higher in raw bauxite used for calcination. Depending on mineralogy and LOI content of ore, about 1.4–1.6 tons of raw bauxite is required to produce 1 ton of calcined bauxite. The process used to manufacture the high alumina cement dictates the physical specification of bauxite.

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.
