在南方离子吸附型稀土矿区,部分在建或拟建的工程建设项目剥离的土方中含有大量的稀土资源,此部分的稀土资源需要及时进行回收。在工程建设项目中,回收已剥离的稀土资源主要采取堆浸工艺,主要步骤为堆场建设、水冶车间建设、工艺操作等。实践证明,稀土抢救性回收堆浸工艺取得了较好的经济效益,回收了宝贵的国家战略性资源。
Abstract：In ion-adsorbed rare earth mining area in southern China,earthwork removed from some construction projects under construction or planned to be constructed contains a large number of rare earth resources,which need to be recovered in time.Heap leaching processes adopted to recover stripped rare earth resources mainly include steps of yard construction,hydrometallurgical workshop construction and process operation,etc.Plant practice proves that salvage recovery heap leaching process of rare earth achieves good economic benefits and recovers valuable national strategic resources.
