  • Method for improved alumina control in aluminum electrolytic cells employing point feeders
    Patent number: 4654130
    Abstract: The present invention describes a method for controlling alumina additions to reduction cells employing point feeders referred to as automatic feed. Automatic feed reduces the possibility of operating the cell at either too low or too high levels of alumina in the bath, and eliminates all anode effects except those desired, thus resulting in increased metal production.
