Net Carbon Consumption is a yield factor that reflects the anode consumption required to produce a unit of aluminum. It is generally expressed in Kg Carbon/metric ton Al.
As a percentage of primary aluminum smelting cost, the carbon anode component represents between 14 and 18% of producing a unit of aluminum. This factor can expand to 30% if poor quality anodes are introduced into the system. Therefore, it is critical for every smelter to focus on carbon anode quality. Simply put, achieving a lower Net Carbon Consumption factor will result in significant cost reduction and greater bottom line profitability.
This model is intended to provide a scope of the favorable financial impact an aluminum reduction plant will achieve by introducing into their system Aminco anodes vs. other anodes of inferior quality.
