Title: The Innovative Contributions of Bruno Marchon

Introduction

Bruno Marchon is a notable inventor based in Paris, France. He has made significant contributions to the field of metallurgy, particularly in the extraction of germanium. With a total of two patents to his name, Marchon's work showcases his expertise and innovative spirit.

Latest Patents

Marchon's latest patents focus on a process for selective liquid-liquid extraction of germanium. This process involves extracting germanium from an aqueous acidic liquor that contains other metals such as cadmium, zinc, cobalt, iron, arsenic, and nickel. The method includes contacting the liquor with an organic medium that contains a diluent and an extractant, ensuring that the diluent is immiscible with the aqueous liquor. The majority of germanium transitions from the aqueous phase to an organic phase, which is then subjected to a stripping step using an alkaline medium. This results in the formation of an aqueous phase that contains the majority of germanium from the original liquor.
