摘要:
铀矿开发过程中产生的低品位铀矿资源被抛弃，造成了严重的环境污染和资源浪费。采用常规浸出技术无法有效提取低品位铀矿、铀尾矿、铀浸渣、含铀废渣等低品位铀矿资源中的铀，为此，强化浸出提铀技术受到了关注。介绍了氧化浸出、焙烧—浸出、微波辅助浸出、超声辅助浸出、微生物浸出、酸碱联合浸出加压浸出、电场辅助浸出等8种强化浸出技术及其机理的研究现状，归纳和总结了目前低品位铀矿资源绿色高效浸出技术的研究方向，为提高铀的浸出率、解决常规技术无法有效提取低品位铀矿资源中铀的难题提供借鉴。
Abstract:Low-grade uranium resources are abandoned in the process of uranium mine development, resulting in serious environmental pollution and resource waste. The conventional leaching technology cannot effectively extract uranium from low-grade uranium resources such as low-grade uranium primary ore, uranium tailings, uranium leaching slag, and uranium-containing waste slag. Therefore, the enhanced leaching technology of low-grade uranium resources extraction attracts more attention. The research progress of eight leaching technologies and leaching mechanisms including oxidation leaching, roasting leaching, microwave-assisted leaching, ultrasonic-assisted leaching, microbial leaching, and pressure leaching are introduced. The green and efficient research direction of low-grade uranium resources leaching technology is summarized, which provides a reference for improving the uranium leaching rate and solving the problem that conventional technology cannot effectively extract uranium from low-grade uranium resources.
