The Bayer Process-The Main Production Method of

2020-11-10  Every kilogram of SiO2 in the ore will cause about 1 kilogram of Al2O3 and 0.8 kilograms of NaOH. The lower the aluminum-silicon ratio of bauxite, the worse the economic effect of the Bayer Process. Until the late 1970s, the aluminum-silicon ratio of the bauxite processed by the Bayer Process was greater than 7-8. As the resources of high-grade gibbsite-type bauxite are gradually decreasing, how to use other types of low-grade bauxite

Precipitation of monohydrate alumina in the Bayer

1996-1-1  The production of alumina by the Bayer process involves three main steps: digestion of bauxite, precipitation of aluminum trihydrate (gibbsite, Al2O3.3H2O) from the resulting solution and calcining of the gibbsite at 980 1200oC to produce alumina. The calcination step absorbs 3 GJ/t alumina or 25% of the total Bayer process.
