Title: Arthur J Tielens: Innovator in Alumina Recovery

Introduction

Arthur J Tielens is a notable inventor based in Zurich, Switzerland. He has made significant contributions to the field of materials science, particularly in the recovery of alumina from bauxite. His innovative methods have the potential to enhance the efficiency of alumina production processes.

Latest Patents

Tielens holds a patent for a method for the recovery of alumina. This process involves recovering coarsely crystalline alumina hydrate from bauxite according to the Bayer process. In this method, fine seed crystals are introduced to form agglomerates in a supersaturated sodium aluminate solution at temperatures ranging from 80 to 65 degrees Celsius. The agglomerates are then processed through a first cascade of crystallizers and subsequently cooled to 55 to 45 degrees Celsius before passing through a second crystallizer cascade. A crystal suspension is extracted from the last crystallizer of the second cascade and is fractionated into fine seed crystals and coarse product crystals.

Career Highlights

Arthur J Tielens is associated with Alcoa Chemie GmbH, where he has applied his expertise in materials science. His work has contributed to advancements in alumina recovery techniques, which are crucial for the aluminum industry.
