Bauxite is processed in a rotary kiln to remove bound moisture so that it can be used as a refractory, a heat resistant material used in a variety of applications. Proppants. Bauxite has also seen growing use as a proppant in recent years. Proppants are used in the hydraulic fracturing process to "prop" open rock fissures allowing natural gas or oil to flow out. Bauxite is sintered in a

Geotechnical Properties Of Raw And Processed Bukit Goh

The average fine material for raw bauxite is 38.40% which should not be greater than 30% per IMSBC Code standard while for processed bauxite is 21.40%. Hence, it is preferable if the bauxite from Bukit Goh mine undergoes beneficiation process before being transported to reduce the risk of cargo liquefaction.

How aluminium is produced

The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be used on high quality bauxite with fairly low content of admixtures, especially silicon.
