Sustainable Mining and Metallurgy

As the gross anode consumption per ton of aluminum is a crucial indicator for aluminum electrolysis and production, reducing this indicator is an effective means to lower production costs and increase economic benefits. Based on the practical production, the height of anode scrap in corners and the middle area of 330kA electrolytic cells was analyzed to explore the viability of reducing the gross anode consumption per ton of aluminum by adjusting the anode height in corners and lowering the anode scrap height in corners. It can be seen from test results that when the anode height in corners drops from 610mm to 600mm, the gross anode consumption per ton of aluminum is decreased by 1.6kg, saving the cost per ton of aluminum and increasing corporate economic benefits.
