A Method for Determining the Productivity of Electrolyzers for Aluminum Production

摘要

The existing methods for determining the productivity of aluminum electrolyzers are systematized. It is shown that the metal-indicator method with copper used as the indicator metal is the most suitable for industrial conditions. The kinetics of dissolution of copper in industrial aluminum electrolyzers is studied and a formula for calculating their productivity is derived. The optimal charge weight of the indicator metal (copper) and the volume of sampling (the number of electrolyzers) are established.
