How is aluminium extracted from bauxite Ore ?Discuss the principle involved in it. how does it react with conc. sulphuric acid ?

Answer 1

By electrolysis we can separate.
In the first step of the process, the alumina is released from the bauxite when it is crushed and dissolved in sodium hydroxide. The resulting solution travels through a number of filters and separators to remove insoluble particles (leaving a liquefied sodium aluminate).

In the second step, the alumina is recovered from this solution when it crystallizes in a precipitation tank. The alumina settles on the bottom, is dried and ground into a find white powder that can be further refined into metallic aluminium.
