Hall’s method is used for the purification of bauxite if it contains both Fe 2 O 3 and SiO 2 in excess. DETAILS OF THE PROCESS: When finely divided bauxite is fused with sodium carbonate it dissolved to form sodium aluminate, while the impurities of Fe 2 O 3 and SiO 2 are left unaffected. Al 2 O 3.nH 2 O + Na 2 CO 3 2NaAlO 2 + CO 2 + (n) H2O

Name the process used for purification of white bauxite ore containing no iron oxide as impurity (A) Baeyer’s process (B) Hall’s process (C) Serpe

The extraction of aluminium involves two steps that is, purification of bauxite by Baeyer's process and electrolysis of alumina. 1. Purification of bauxite by Baeyer's process In the Baeyer's process, the bauxite ore is heated with concentrated NaOH solution under pressure (Aluminum is purified by leaching method).The alumina dissolves as sodium meta aluminate

iii) Hall’s process : This process is used when both Fe2O3 and SiO2 is present as impurity. Bauxite is fused with Na2CO3 then sodium aluminate is obtained. The molten mass is dissolved in boiling water. Impurity of Fe2O3 is filtered out. the filtrate contains sodium meta aluminate and Na2SiO3. Al2O3 . 2H2O + Na2CO3——— 2 NaAlO2 + CO2 +2 H2O

Observe the following statements regarding purification of bauxite: I. During Hall's process, silica is removed as Si (vapour). II. Bauxite ore contaminated with F e 2 O 3 is purified in Baeyer's process. III. During Serpeck's process, A l N is formed

Write Three Balanced Equation for the Purification of Bauxite ? - Chemistry. Aluminium is extracted from its chief ore, bauxite. The ore is first purified and then the metal is extracted from it by electrolytic reduction. Write three balanced equation for the purification of bauxite ?

In purification of Bauxite by Hall's process : A. it is heated with NaOHsolution at 500C. B. it is heated with NaHCO3 . C. bauxite ore is heated with Na2 CO3 . D. none of these
