History of the Bayer Process: Bayer process was invented by Austrian chemist, Carl Josef Bayer in 1887, while working in Saint Petersburg, Russia for developing a method to supply alumina to the textile industry The Bayer process started gaining importance after the invention of Hall-Heroult aluminium process
alumina beneficiation st and process Today the Bayer process dominates the production of alumina as it is the lowest cost production route The process uses a recirculating volume of concentrated caustic solution to dissolve the alumina minerals, separate them from still solid impurities, and then re-precipitate alumina tri-hydrate
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef BayerBauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide The aluminium oxide must be purified before it can be refined to .
