LONG-DISTANCE TRANSPORT OF BAUXITE SLURRY BY PIPELINE

bauxite from mine to alumina refinery over long distances are by rail or conveyor. Bauxite is delivered to the refinery relatively dry as run of mine ore ready for feed into the plant crushing/ grinding circuit. However, an alternative means of transport gaining attention is to prepare a slurry from the bauxite ore at the mine and pump it through a
