Abstract

The present disclosure relates to systems, methods, and apparatus for extracting molten liquid from an electrolysis cell. In one embodiment, a system includes a container and an electrical characteristic detector. The container comprises a body adapted to contain molten liquid and a spout. The spout includes a base portion, a tip portion and a passageway connecting the base portion to the tip portion. The electrical characteristic detector is coupled to the container and is configured to determine an electrical characteristic associated with the molten liquid as the molten liquid passes into the body of the container via the passageway. A process parameter associated with the removal of the molten liquid from the container may be changed when it is determined that an electrical characteristic associated with the molten liquid has achieved a predetermined threshold.
