Title: Innovations of Elena L Shalavina in Gallium Extraction
Introduction
Elena L Shalavina is a notable inventor based in Alma-Ata, SU. She has made significant contributions to the field of gallium extraction, holding 2 patents that showcase her innovative methods. Her work focuses on improving the efficiency and cost-effectiveness of gallium recovery from various solutions.
Latest Patents
One of her latest patents is a method for the extraction of gallium from aluminate-alkaline solutions. This method involves a two-stage carbonization process that produces aluminum oxide hydrate and a gallium-containing precipitate. The gallium precipitate is then mixed with a caustic alkali solution to achieve a gallium concentration of 0.05 to 1 g/l. The process allows for the separation of gallium and the production of valuable alkali metal salts from low-grade ores.
Another significant patent is a process for recovering gallium from alkali aluminate solutions. This process includes neutralizing the starting alkali aluminate solution and evaporating it to a higher concentration of caustic alkali. The solution is then treated with a liquid alloy of gallium, resulting in a concentrate containing over 90% gallium by mass. This method not only enhances the purity of the recovered gallium but also minimizes costs and equipment requirements.
