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.
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.
(iii) Lead metal is obtained by the process of smelting which uses carbon as the reducing agent. So, the statement is true. (iv) Serpeck method is used for the purification of white bauxite and not red bauxite. So, the statement is false. Based on the above observations we can conclude that the correct order is TFTF.
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 ().
The ore is first concentrated by leaching either by Bayer's process for red bauxite (impurity: FeX2OX3 F e X 2 O X 3) or by Serpeck's process for white bauxite (impurity: SiOX2 S i O X 2 ). Then alumina is reduced electrolytically via HallHéroult's process directly to 99% pure aluminium.
Process Y (Serpeck's process): applied for white bauxite to remove Z (chief impurity) then process X and impurity Z are: Medium. View solution > In the extraction of aluminium, ... Red Bauxite is purified by Serpeck's Method. Medium. View solution > View more. CLASSES AND TRENDING CHAPTER.
Step by step video, text image solution for In the extraction of aluminium Process X: employed for red bauxite to remove iron oxide (main impurity) Process Y: (Serpeck's process): used for while bauxite to remove Z (main impurity) then, Select correct option for the process X and impurity Z. by Chemistry experts to help you in doubts scoring excellent marks in Class 12 exams.
Bauxite is the principle ore of aluminum having the chemical name hydrated aluminum oxide with the chemical formula Al 2 O 3. 2 H 2 O. Impurities present in bauxite are iron oxides such as hematite ( Fe 2 O 3) and geothite ( FeHO 2), silicon dioxide SiO 2, the clay mineral kaolinite Al 2 O 3. 2 SiO 2. 2 H 2 O and a small amount of titanium ...

Serpeck's process. D. Hall's process. Medium. Open in App. Solution. Verified by Toppr. Correct option is C) White bauxite containing the impurity of silica only in removed by heating with coke in atmosphere of nitrogen. A ...
Process X: applied for red bauxite to remove iron oxide {chief impurity} Process Y: (Serpeck's process) : applied for white bauxite to remove z {chief impurity} then process X and impurity Z are_____.
Correct options are B), C) and D) Bayer's process: Bauxite ore contains impurities like Fe 2O 3,TiO 2,SiO 2 . When it dissolves in aq. NaOH/pressure + 150°C, bauxite dissolves but the impurities do not.
For (i) Baeyer's process; for (ii) Serpeck's process. Iron oxide impurity Baeyer's process: In Baeyer's process, impure bauxite is converted into pure alumina. The conversion process involves mainly three reactions. ... Consider the process for concentration of bauxite. Process 1 : Employed for red bauxite to remove main impurity iron oxide.

Solution. To transport the first set of data, use the following method and then schedule a duplicate backup job to start optimized duplication. Back up your data to disk or to tape using Backup Exec or NetBackup. Transport the tape or disk to the destination system (CAS or MMS) On the destination, inventory and catalog the data.
In the extraction of aluminium Process X: applied for red bauxite to remove iron oxide {chief impurity} Process Y: (Serpeck's process) : applied for white bauxite to remove z {chief impurity} then process X and impurity Z are_____.
In the Bayer process, the insoluble product generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure to produce alumina is known as red mud' or bauxite residue'. (1) Roughly tons of red mud wastes are generated per ton of aluminum produced.
Solution Verified by Toppr Correct option is B) Bayer's process is used for benficiation of red bauxite. Serpeck's process is used for benficiation of white bauxite. Reaction to remove impurity; SiO 2+2C→Si+2CO Video Explanation Was this answer helpful? 0 0 Similar questions
