PURIFICATION OF ALUMINUM THROUGH Al2O3 – AlF3 ACTIVE FILTRATION

Abstract

Filtration is the most cost effective method to purify aluminum. In this paper, filtration experiments have been carried out using both AlF3 slurry coated, and uncoated Al2O3 ceramic foam filter (CFF) to study the removal of both nonmetallic inclusions and impurity elements. The results showed that the 30 ppi CFF removed up to 85% inclusions from aluminum… (More)
