Review of methods for processing ore vanadium-containing raw materials

Abstract

The article discusses the methods of processing vanadium-containing raw materials, including methods of pre-sintering and leaching of raw materials, extraction and precipitation of vanadium-containing solutions. In addition, the specific methods used for each type of vanadium-containing raw materials are described, with a description of their advantages and limitations. The article also briefly analyzes a number of the main influencing factors and mechanisms of various processes. Some research prospects are proposed to improve the methods of vanadium concentration from vanadium-containing raw materials. The article considers the potential of extraction and processing of vanadium-containing black shale ore, as well as vanadium-containing titanomagnetite ores. Spent vanadium catalysts used in petrochemical processes can be a potential source for vanadium extraction. In addition, vanadium-containing bauxite raw materials, oil and steel production slags can be promising raw materials for further extraction of vanadium.
