At most Australian bauxite mines, the ore is crushed and then transported by conveyor and/or railway to the refineries. The only significant difference occurs at Comalco -Weipa, where the bauxite is crushed, washed (to remove some of impurities such as clay minerals, coarser silica and organic compounds) and then dried prior to transport to the alumina refinery.
