Serpeck's Process: When silica is present in significant proportions in bauxite ore, this technique is used. The ore is combined with coke and heated to 1800°C in the presence of nitrogen, resulting in the formation of AlN (aluminium nitride). ... Because the ore is usually red in colour, it is known as red bauxite. Q4. Aluminium being more ...

Bayer's process will be uneconomical due to generation of insoluble sodium aluminium silicate. Aluminium ore is also called bauxite. The bauxite is purified to produce aluminium oxide, which is a white powder and aluminium can be extracted from it. The extraction is done by the process of electrolysis. Note: Red Mud is the waste product that ...

Serpeck's process This process is used for the purification of bauxite ore containing silica (SiO2) as the main impurity. The powdered ore is mixed with coke and the mixture is heated at about 1800°C in the presence of Nitrogen gas, when aluminium nitride is formed. Al2O3. 2H2O + 3C + N2 → 2AI N + 3CO+ 2H2O

tonnes for high grade bauxite to tonnes for the very low grade. Wang and Liu [16] have documented that red mud from the Bayer process consists of dispersive particles compared to sintering red mud. The specific gravity of the Bayer red mud () determined by pycnometry is higher than that of the sintering red mud ().

Bauxite 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.

Solution. 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 ...

Solution. The correct option is D Leaching. Bauxite ore is concentrated by the process of leaching. It is a process in which a suitable solution is added to the ore. A chemical reaction takes place between ore and solution in which the ore dissolves in the solution. The insoluble impurities are filtered off.

3 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.
