Halls' Process: Red Bauxite is fused with sodium carbonate to form sodium meta aluminate which is extracted with water. The impurity Fe 2 O 3 is filtered out. Al 2 O 3 + Na 2 CO 3 → 2NaAlO 2 + CO 2 Into the solution of sodium meta aluminate, CO 2 gas is passed to precipitate Al(OH) 3. The precipitated Al(OH) 3 is ignited at 1200°C to get ...
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite [].Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about 7% to below 3%, to make this one the best metallurgical grade ...

The bauxite powder is mixed with carbon and heated under high temperature (above 1800^circ C) and a current of nitrogen is passed. Through this process aluminium nitride is obtained along with water and carbon monoxide. For the given question, let's understand how the process works and then identify the reaction matching the process.

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 Bayer's method and Hall's method is used for the red bauxite which contains F e 2 O 3 and silicates as impurities. Serpeck's method is used for the white bauxite which containes silica as impurities.
Complete step by step answer: In this question we have asked about the purification of Bauxite by Serpeck's reaction. So, first of all, what is bauxite? Bauxite is a form of sedimentary rock and is the principal source of the popular metal aluminium. The chemical formula of bauxite is A l 2 O 3 .2 H 2 O.
(X) Red bauxite contains the impurities of oxides of iron and silicates. In Bayer process, alumina is dissolved by reacting sodium hydroxide solution leaving behing the insoluble oxide of iron. (Y) White bauxite contains the impurity of silica which is removed by Serpeck's method A 1 2 + N 2 + 3 C 1800 ∘ C − −−− → 1 A 1 N + 3 C O,
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.
