Title: **Sukumar Mandal: A Trailblazer in Vanadium Recovery Innovations**
Introduction
Sukumar Mandal, an accomplished inventor based in Haryana, India, has made significant contributions to the field of materials recovery, particularly in the extraction of vanadium from gasifier slag. With an impressive portfolio of 32 patents, he is renowned for pioneering processes that enhance the sustainable recovery of valuable metals from industrial waste.
Latest Patents
Among his latest innovative patents are two notable processes aimed at obtaining vanadium oxide and iron vanadate from gasifier slag.
The first patent, **"Process for obtaining vanadium oxide from a gasifier slag,"** discloses a method that starts with pulverizing the slag to create powdered material. This is blended with water and an alkali salt to form a slurry, which is then dried and roasted in the presence of air. The process efficiently leaches the roasted slag to produce a first filtrate rich in vanadium. Subsequent chemical reactions with magnesium and ammonium salts yield ammonium metavanadate, which is further calcined to produce vanadium pentoxide, a valuable compound.
The second patent, **"Process for recovering vanadium in the form of iron vanadate from a gasifier slag,"** outlines a similar initial procedure of pulverizing and soaking the slag. This is followed by roasting and leaching to derive a first solution, which is then treated with an iron salt under controlled temperature and pH conditions. The resultant iron vanadate is dried to provide a product that could be integral to various industrial applications.
Career Highlights
Sukumar Mandal has held notable positions in prestigious companies such as Reliance Industries Limited and Indian Oil Corporation Limited.
