Title: Michel Ferran: Innovator in Alumina Production
Introduction
Michel Ferran is a notable inventor based in Aix-en-Provence, France. He has made significant contributions to the field of materials science, particularly in the production of pure alumina. His innovative approach has led to the development of a unique process that enhances the efficiency of alumina extraction.
Latest Patents
Michel Ferran holds a patent for a continuous process for obtaining pure alumina from an acidic liquor. This process involves several steps, including the chlorosulphuric attack of calcined aluminous ores containing impurities. Following this, the liquor obtained after the attack is concentrated, and the sterile material is separated. The process further includes the treatment of the concentrated liquor with sulphuric acid, followed by chlorination to precipitate almost all the hexahydrated aluminum chloride. The precipitate is then separated from the chlorosulphuric mother liquor, which is charged with impurities. The pyrohydrolysis of the precipitate yields the desired pure alumina, while recycling released hydrochloric acid. Additionally, the chlorosulphuric liquor is degassed to remove impurities, and the remaining impurities are eliminated through sulphuric precipitation in the presence of potassium ions.
