Mossbauer spectroscopy used to study the removal of iron from clay.
Metall Trans B 1984 Dec; 15B:732-734
Domestic kaolinitic clay represents a vast, and accessible, potential source of aluminum that could conceivably be used to produce the refractory oxide, used as a substitute for imported bauxite, or used as a feed for the chlorination route to the metal. Long-range research efforts within the Bureau of Mines have pursued each of these concepts, and in each, the small amount of iron has been a major concern. Using Mossbauer spectroscopy, the Bureau has shown the chemical state of the contained iron before and after treating kaolin, and presents these analyses as a basis for judging the feasibility of iron removal by the treatments used here.
