Red muds are non-recyclable wastes formed after bauxite processing, occupy significant areas and are environmentally hazardous. At the same time, red mud contains a large number of valuable components - rare earth metals, iron and titanium. The thesis analyzes the existing technologies for processing red mud and the effectiveness of existing methods for extracting valuable components from red mud. The aim of the study was to study the leaching of red mud in sulfuric acid in order to extract iron into a solution and concentrate titanium in an insoluble residue. As a result of the work, optimal leaching conditions were established, ensuring removal of iron from red mud by 80% and concentrating up to 70% of titanium in an insoluble residue.
