Title: Bertrand Berthomieu: Innovator in Hydrometallurgical Processes
Introduction
Bertrand Berthomieu is a notable inventor based in Rambouillet, France. He has made significant contributions to the field of hydrometallurgy, particularly in the treatment of lateritic nickel and cobalt ores. His innovative approaches have the potential to enhance the efficiency of metal extraction processes.
Latest Patents
Berthomieu holds a patent for a process aimed at the hydrometallurgical treatment of lateritic nickel/cobalt ore. This process involves a mixture of limonite and saprolite, which is treated in the presence of an iron-precipitating agent. The mixture is transformed into a pulp with a solids content ranging from 10 to 40% by weight. The pulp undergoes a leaching operation with sulphuric acid at temperatures between 70°C and the boiling point, followed by a solid-liquid separation. This results in an iron-containing solid residue and a solution rich in nickel and cobalt ions. The process also outlines methods for producing nickel and/or cobalt intermediate concentrates or commercial products.
