Advanced purification cell for aluminum scrap recycling

Abstract

The present disclosure includes a method for purifying aluminum. The method includes producing purified aluminum from an aluminum feedstock in an aluminum purification cell and flowing the purified aluminum from a cell chamber of the aluminum purification cell to a purified metal reservoir via an overflow passage, wherein the purified metal reservoir is located internal to the aluminum purification cell. In some embodiments, a feeding reservoir is located internal to the aluminum purification cell and can be accessed via a feeding port located in a refractory top cover of the cell chamber. In some embodiments, the method includes removing the purified aluminum from the purified metal reservoir via a tapping port located in a refractory top cover of the cell chamber. In some embodiments, concomitant with the removing step, the method includes restricting or preventing oxidation of the purified aluminum.
