Bauxite Mining The Australian Aluminium Council

Bauxite Mining. 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 ...

Beneficiation of bauxite

2011-8-11  A schematic flow diagram for the proposed beneficia-tion plant is given in Fig. No. 1. In the proposed in-stallation, the run-of-mine ore would be fed to a Double Pitman Jaw Crusher by means of an apron conveyor. The crushed bauxite would be first chuted down to a scalping screen where the larger lumps up to 2-inch size would be separated.

Chapter 2. Production and Processing of Aluminum

1999-5-7  Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.
