1.	How is ore of aluminium concentrated ?A. roastingB. leachingC. froth floatationD. using wilfley table
Answer» Correct Answer - b Leaching is the method of extraction of aluminum form its ore (bauxite) by the treatment of powdered ore with a concentrated solution of NaOH resulting in dissolution of `AI_(2)O_(3)` leaving impurities behind as `AI_(2)O_(33)(s)+2OH^(-)(aq)+3H_(2)Orarr 2[aI(OH)_(4)]^(-)(aq)` This Process is called bayer process
