The extraction of aluminium involves two steps that is, purifiion of bauxite by Baeyer's process and electrolysis of alumina. 1. Purifiion 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.
Answer (1 of 2): Because the major impurity in bauxite is iron(III) oxide, which is a basic metal oxide. Treatment with sodium hydroxide dissolves the amphoteric Al₂O₃, but leaves the iron(III) oxide undissolved (it's filtered off). Al₂O₃ + 2 OH⁻ + 3 H₂O ⇌ 2 [Al(OH)₄]⁻
