Title: The Innovative Contributions of Andre Georgeaux
Introduction
Andre Georgeaux is a notable inventor based in Rambouillet, France. He has made significant contributions to the field of hydrometallurgy, particularly in the recovery of lead from sulphurized compounds. With a total of seven patents to his name, Georgeaux's work has advanced the methods used in metal recovery processes.
Latest Patents
One of his latest patents is a hydrometallurgical process for the treatment of sulphidized compounds. This invention provides a method for recovering lead in essentially pure form from a sulphurized compound containing lead as a non-ferrous metal. The process involves treating the sulphurized compound with an aqueous lixiviating solution containing at least one chloride of a metal selected from copper, bismuth, antimony, arsenic, and silver, preferably cupric chloride. The quantity of the chloride used is less than or equal to that which is stoichiometrically required for the complete dissolution of the lead. This results in a solution containing lead chloride and the chlorides of nobler metals as impurities, along with an insoluble residue. The lead chloride solution is then separated and purified, ultimately allowing for the recovery of metallic lead.
Another significant patent involves a process for the treatment of solutions of lead chloride, which contain impurities such as silver, copper, and bismuth. This process outlines specific steps to effectively treat these solutions, enhancing the efficiency of lead recovery.
