Title: Helmut Junghanss: Innovator in Manganese Nodule Processing
Introduction
Helmut Junghanss is a notable inventor based in Duisburg, Germany. He is recognized for his contributions to the field of hydrometallurgy, particularly in the processing of manganese nodules. His innovative methods have implications for the recovery of valuable metals from these nodules.
Latest Patents
Helmut Junghanss holds a patent for a method for processing manganese nodules and recovering the values. This method involves suspending raw manganese nodules in water or a dilute wash solution to create a suspension. The suspension is then combined with sulfuric acid in a pressure vessel, where it is heated to selectively leach nickel, copper, cobalt, and zinc from the nodules. The resulting metal-rich leach solution is separated from the residue, allowing for the recovery of these valuable metals.
