of tantalum ores from leucogranite and alluvial deposits is presented. This study will be used as a basis for designing the milling experiments to optimize the tantalum recovering during the processing. In the ore deposits, tantalum appears as a solid solution with niobium forming complex oxides which constitute small size aggregates.
