Question

Explain the process of leching with reference to concentration of bauxite ore

Answer 1

Explanation:

Bauxite usually contains silica, iron oxide, and titanium oxide as impurities. In the process of leaching, alumina is concentrated by digesting the powdered ore with a concentrated solution of NaOH at 473-523 K and 35-36 bar.
