| 摘 要： | 沉积型铝土矿是我国主要的铝土矿类型,经过几十年的开发,储采比逐渐下降,深部难动用资源的绿色开发迫在眉睫. 通过开展静态溶浸实验和电极加热仿真模拟,结合原位溶浸技术在铀矿和稀土矿开采中的成功经验,总结出该技术在固体矿产开采中应用的适用条件包括:矿物可溶性、矿体分布稳定性、顶底板条件、矿体渗透性. 我国北方铝土矿资源与以上条件切合程度高,适合采用原位溶浸技术进行开采. 本次研究还提出了沉积型铝土矿原位溶浸开采的工艺方案,为下一步开展先导试验提供了设计思路.

| Abstract: | Sedimentary bauxite is the main type of the deposits in China. The reserve-production ratio has gradually declined with decades of development, thus green exploitation of difficult-to-use resources in the deep is a matter of great urgency. Through static leaching test and electrode heating simulation, combined with the successful experience of in-situ leaching technology in uranium and rare earth mining, the application conditions of the technology in solid mineral mining are summarized as follows:1) soluble minerals, 2) stable orebody distribution, 3) roof and floor conditions and 4) orebody permeability. The bauxite resources in North China fit in well with the above conditions and are suitable for in-situ leaching technology. The technological scheme for in-situ leaching mining of sedimentary bauxite is also proposed, which provides idea for pilot test design in the next step. |
