Removal of Impurity Elements from the Molten Aluminum: Modeling and Validation

In order to remove impurity elements like H, Na, Ca, Li from the molten aluminium, many processes, such as injecting inert or reactive gases, reactive or unreactive powders, and slag refining, have been used in last several decades. In the current paper, mathematical models for the removal of impurity elements from molten aluminium in the batch and continuous reactor were developed and validated with industrial measurements
