摘　　要：离子型稀土资源开采在现行技术条件下无论采用原地浸矿还是堆浸工艺均会产生负外部性,通过对原地浸矿、堆浸工艺条件下离子型稀土资源开采负外部性表现形式以及基于现代控制理论对离子型稀土资源开采负外部性的能控性和能观测性的简要分析,得出以下初步结论:①离子型稀土资源采用原地浸矿工艺开采的负外部性的能控性会难于采用堆浸工艺;②离子型稀土资源采用堆浸工艺开采的负外部性的能观测性会比采用原地浸矿工艺容易。此外,建议进一步优化原地浸矿、堆浸工艺,再从离子型稀土资源开发全过程及其负外部性的能控性和能观测性角度系统比较这两种工艺,明确各种浸取工艺的适用条件。The mining of ion-adsorption rare earth resources will cause negative externalities regardless of in-situ leaching or heap leaching process under the current technical conditions.By analyzing the manifestations,the controllability and observability of negative externalities during the mining of ion-adsorption rare earth resources based on modern control theory,the conclusions are drawn as follows:①The controllability of the negative externalities of ion-adsorption rare earth resources mined by in-situ leaching process will be more difficult than that by heap leaching process;②The observability of the negative externalities of ion-adsorption rare earth resources mined by heap leaching process will be easier than by in-situ leaching process.In addition,it is recommended to further optimize in-situ leaching and heap leaching processes,and then systematically compare the two processes from the perspective of the whole process of resource mining and the controllability and observability of the negative externalities,and clarify various leaching processes applicable conditions.
