The Process of Mining Bauxite - Dajcor

Feb 27, 2019 · The calcining kiln is brick-lined inside and gas-fired to a temperature of 1,100°C. It slowly rotates and is mounted on a tilted foundation which allows the alumina to move slowly through it to cooling equipment. Alumina is formed into a white powder, this is the final product of the Bayer Process, ready for shipment to aluminum smelters.

Oct 28, 2021 · Step 1- Crushing process. The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area of the bauxite greatly increases, which helps to speed up the follow-up speed of the chemical reaction.

Mining and Refining – Process - World Aluminium

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.
