Question
Chemical leaching is useful in the concentration of :
Options
A.carnallite
B.bauxite
C.galena
D.zinc blende
Solution
Al2O3(s) + 2NaOH(aq) + 3H2O(l) → 2Na[Al(OH)4](aq)
2Na[Al(OH)4] (aq) + CO2(g) → Al2O3.xH2O(s) + 2NaHCO3(aq)
Al2O3.xH2O(s)
Al2O3(s) + xH2O(g)
2Na[Al(OH)4] (aq) + CO2(g) → Al2O3.xH2O(s) + 2NaHCO3(aq)
