Abstract

Column leaching is one of the experimental methods which is used for identifying the specifications of uranium ores. From the efficiency point of view, the process has some complications and usually it is applied in parallel with the conventional leaching process in order to facilitate of finding an appropriate design and operational method, to be applicable in a large practical scale. In this research work, at the first stage, the existed free chlorine in the samples was washed out using seawater. Then, in a process of acid leaching with seawater and sulfuric acid by the use of the COLUMN LEACHING was applied. The results show that the maximum of 85% of uranium from the ore of Anomali #1 is extracted. The extra residual of the used acid dose not react with the uranium and therefore it will increase the free acidity of the LEACH LIQUOR. In Anomali #6, the extraction efficiency of uranium is 75%, while in Anomali #8, using 30 periods of leaching, the efficiency is 81%. However, the maximum efficiency achievement has to be avoided by the non-economical circumstances. Based on some comparisons, it is shown that the presence of chlorine in ore will affect the efficiency. The capability of "seawater" in uranium extraction from SALTED ARCHES SHAPED, compared with the "normal or sweat water" has some advantages. These include: reduction of the operational period, less acid consumption, and reduction in the ore leaching costs. Thus, the HEAP LEACHING industry is believed to be a valuable and economical method for uranium extraction, where the needs for utilizing the complicated technical facilities can be reduced. The present work is the first research project on the uranium extraction and concentration in solution containing chlorine. Our experimental results can provide a valuable pattern for the HEAP LEACHING of uranium ores design from SALTED ARCHES SHAPED in the region Bandar Abbas.
