The paper presents the results of developing a method for producing nanopowder (Fe-Co) in the form of a solid solution by precipitation from vanadium-containing raw materials of the hydrometallurgical plant Balausa Firm LLP. Solutions obtained by leaching black shale ores with an iron content of up to 4-6% to obtain iron-containing powders were studied. X-ray phase analysis has established that the initial iron content of 2 to 6% is sufficient for applying the scheme for extracting iron sulfate and obtaining powders based on it from solutions obtained by leaching black shale ores. By the results of electron microscopy analysis, was established that the size of crystallites in the resulting powders (Fe-Co) is 30-50 nm and that of their agglomerates is 100-200 nm.
