[Kannada] Describe the three steps involved in the leaching of bauxite
(a) Bauxite ore is heated with concentration solution of NaOH at 473 K to 523 K and 35-36 bar pressure. Al(2)O(3) dissolves out as sodium aluminate leaving behind impurities. Al(2)O(3) + 2NaOH + 3H(2)O rarr 2Na[Delta l(OH)(4)] (b) The aluminate in solution is neutralised by passing CO(2) gas and hydrated Al(2)O(3) is precipitated.
