稀土矿物（英语：Rare earth mineral）是指主要成分包含一种或是多种稀土元素的矿物。稀土矿物通常发现于碱性至过碱性火成岩组合中、与碱性岩浆伴生的伟晶岩中，或是存在/伴生于碳酸盐深成岩中。^[1]具有钙钛矿结构的矿物是稀土元素碱性错合物的常见宿主。^[2]来自地幔的碳酸盐熔体也是稀土的载体。^[3]与碱性岩浆作用相关的热液矿床含有多种稀土矿物。^[1]

而稀土元素是一组共17种，银白色、质软、具有光泽，但彼此性质相似难以区别的金属元素。^[4]^[5] 虽然名为稀土元素，但实际上这些元素在地壳中的数量相对丰富，其中丰度最高的铈是地壳中排名第25常见的元素（参见地壳元素丰富度列表），占68百万分率，含量超过铜。然而，由于稀土元素的地球化学特性，它们在地壳中分布通常十分分散，而罕有富集到高浓度的稀土矿物存在，因此世界上少有具开采价值的矿场，故得“稀土”之名。^[6]

中国的储藏量占全世界的36.7%，^[7]但中国的产量曾占全世界的95%以上，^[8]在2017年占全世界的81%。到2021年中国的产量占全世界的60.63%，而同年美国的产量排名第2，占比为15.52%。^[9]

中国的白云鄂博矿区是世界已知最大的稀土矿物蕴藏区。^[10]在2005年，这个矿区的稀土元素产量曾高达全世界的45%。^[11]^[12]^[13]

常见稀土矿物

以下所列的是比较常见的热液稀土矿物，以及经常含有显著稀土元素替代物的矿物：^[14]

钇易解石或铈易解石
褐帘石
磷灰石
氟碳铈矿（英语：bastnäsite）
铈硅磷灰石（英语：Britholite-(Ce)）或钇硅磷灰石
板钛矿
硅铈石
硫硅酸盐绿帘石Dollaseite-(Ce)（英语：硫矽酸鹽綠簾石Dollaseite-(Ce)）
氟铈石（英语：fluocerite）
萤石
硅铍钇矿
独居石
氟碳铈钙石（英语：Parisite-(Ce)）或氟碳镧钙石（Parisite-(La))
菱硼硅铈矿（英语：Stillwellite-(Ce)）
直碳钙铈矿（英语：Synchysite-(Ce)）
榍石
氧钒钇矿（英语：wakefieldite）
磷钇矿
锆石

开采作业对环境的可能影响

在自然环境中的稀土元素浓度非常低。蕴藏这类资源的矿山通常位于环境和社会标准非常低的国家，因为矿山的开发，而导致有侵犯人权、森林砍伐的事情，并且污染到当地的土地和水源。^[15]^[16]

在采矿和工业生产场所附近，稀土元素的浓度会上升到正常背景水准的许多倍。稀土元素一旦进入环境，就会渗入土壤中，然后它们的迁移取决于多种因素，例如侵蚀作用、风化作用、pH值、降水和地下水等。如同金属一样，它们可根据土壤条件形成，无论是移动，或是被吸附到土壤颗粒中。根据它们的生物利用度，稀土元素可被植物吸收，然后被人类和牲畜摄入。对于稀土元素的开采，使用（肥料添加剂）和磷肥的生产，都会导致稀土元素污染。^[17]此外，在萃取稀土元素的过程中会用到强酸，而这些酸会渗入环境，并通过水体而导致水生环境酸化。

对于稀土元素的开采、提炼和回收，如果管理不当，会对环境造成严重后果。稀土元素尾矿中的钍和铀因有低放射性，而存有潜在危害，^[18]这些物质如果处理不当，会对环境造成广泛的伤害。
