WhatsApp: +86 18838072829Solution. Reduction of Al2O3 is not performed by carbon due to two primary reasons which are:. Very high temperatures around 2100 degree celcius is required for the carbothermic reduction. Aluminium Oxide is a very stable oxide and lies below the the oxidation line of carbon in Ellingham Diagram hence Al2O3 cannot be reduced by carbon as it is ...

WhatsApp: +86 18838072829Bauxite is Al 2O 2O. Water molecules and other impurities are removed from it to make it pure Al 2O 3. By leaching in the Bayer's process, pure Al 2O 3 obtains. When a sulphide ore is roasted, it turns to oxide ore. Here the ore is oxidized and the ore acts as reducing agent. So sulphate part acts as reducing agent.

WhatsApp: +86 188380728293 Answers Sorted by: 3 From this source Baeyer's process: This method is mainly applied when ferric oxide is present as chief impurity. Serpeck's process: This process is used when silica is present in considerable amount of bauxide ore. I couldn't find any information on the efficiency, but I suspect both are efficient in their own way.
