- Sainmhíniú in a primary aluminium plant, anode manufactured in a carbon plant from a mixture of calcined petroleum coke and coal tar pitch that is formed into a block and baked in an anode furnace Tagairt COM-EN, based on: Patrick Finlay. Primary aluminium production. Draft Guidelines on Best Available Techniques (BAT) for Primary Aluminium http://www.pops.int/documents/meetings/bat_bep/2nd_session/egb2_followup/draftguide/6b2primaryaluminiumdraft.pdf [10.1.2012]
- Nóta They are gradually lowered into the pots as they are consumed, and need to be replaced before the entire block has been consumed. The anode remnants, known as anode “butts”, are cleaned and returned to the carbon plant for recycling. Depending on the method of feeding the alumina into the electrolytic cells, the cells are called Side-Worked Pre-Bake (SWPB) or Center-Worked Pre-Bake (CWPB). For SWPB cells, the alumina is fed to the cells after the crust is broken around the perimeter. For CWPB cells, the alumina is fed to the cells after the crust is broken along the centreline or at selected points on the centreline of the cell.
