Alkaline Leaching Of Aluminium Black Dross

alkaline leaching of mechanically activated black dross resulted in an aluminate(iii) solution with a small amount of silicate(iv).To obtain pure aluminate(iii) solution, the removal of silicate(iv) from the alkaline leaching solution was investigated by adsorption with hydrocalumite (ca2al(oh)6cl2h2o).The hydrocalumite was synthesized by the coprecipitation method.
