Factors Affecting the Preparation of Misted Clay Feed and Solids-Liquid Separation After HC1 Leaching

摘要

Although aluminum is easily leached from calcined clay with boiling mineral acids, the presence of fines and slimes in the leached residue has hindered the application of acid leaching processes. A feed preparation method was, therefore, devised that provided a dense, smooth-surfaced, fine-grained clay.
