The leaching behaviour of a uranium ore, with sulfuric acid and sodium chlorate, has been investigated in agitated tanks. Data from conventional leaching studies has been supplemented with mineralogical characterisation and SEM analysis of selected samples. A technique known as block leaching was also used, which allows individual grains of both the ore and gangue minerals to be studied before and after leaching under different conditions. As a result of the experimental investigation a detailed description of the leaching behaviour of the ore has been compiled.
