Analysis of pegmatitic granite-uranium deposit formation conditions and exploitation prospects in the Shaanxi Shang-Dan triangular region, China

Abstract

By adopting a new deposit formation theory, that is, that landscape, field, mineragraphy and deposit evolve in turn to form a mineral deposit, together with combining macro and microanalysis, we have analyzed the geological environment, deposit formation mechanisms and prospects of uranium deposit formation in the Shang-Dan triangular region. We conclude that a uranium mine with resource/reserves of ten thousand tons might be verified in the Shang-Dan triangular region following geologic exploration. Heap leaching technology and research at different scales have been conducted on ore from the Guangshigou uranium deposit. This deposit is located in this region. In this research, systematic and economically rational processing flow and technical parameters were acquired, which were up to the domestic advanced level of the same field and there had been no preceding pegmatitic granite uranium ore heap leaching technique in China. Scientific foundation has been laid for the exploration and exploitation of this uranium mineral deposit and other deposits of the same kind. There are good prospects for the exploration and exploitation of pegmatitic granite uranium deposits.
