南方离子型稀土矿开发中的资源环境问题与对策

Resource and environmental issues and countermeasures in exploiting ion-absourbed rare earth elements ores of South China

南方离子吸附型稀土矿是我国特有的一类矿床,其形成与当地的地质地貌和气候条件有关。由于开采容易,品质高,配分好,市场需求大,曾在上世纪末形成一阵开采热潮,相应地也产生了一些环境问题,主要是如何防止资源浪费,治理水土流失和生态恢复;认为这些问题在有效管理的基础上,通过工程手段是容易解决的。

Ion-absorbed REE(Rare earth elements)ore of south China is a novel type mineral which is absorbed on clay particles at ionic state only found in our country,whose formation is relevance to local geology,physiognomy and climate statues.Due to its advantages in ex-ploiting and components,an upsurge had been appeared from1986to1999,and therefore brown up some problems to resource and environ-ment.They are how to stop wasting resource,how to control soil erosion and how to do ecological restoration work.By investigating on the spots,author thought that at the base of effective management,these problems are ease to be solved with eco-technological approaches.
