Aluminium - Fives in Air Pollution Control

Primary aluminium producers have to continuously improve their emission levels to meet the most stringent environmental regulations. They must treat pollutants emitted during the electrolysis process, such as HF, due to the adsorption process of fluorine by alumina, as well as PAHs and dusts emitted during the anode baking and manufacturing.

Environmental Guidelines for Aluminum Manufacturing

2018-8-5  Primary aluminum is produced by the electrolytic reduction of the alumina. The alumina is dissolved in a molten bath of fluoride compounds (the electrolyte) and an electric current is passed through the bath which causes the alumina to dissociate to form liquid aluminum and oxygen which reacts with carbon in the electrode to produce carbon dioxide and carbon monoxide. Molten aluminum
