这份报告提出了一些预测矿区金属流动性的策略。这些策略基于有关金属及其与环境相互作用的化学、物理和地球化学信息。概述了概念模型，金属来源，和相对流动性的金属在不同的地球化学条件下，其次是一些重要的物理和化学性质的金属，影响其流动性，生物利用度和毒性的讨论。物理和化学性质导致讨论金属化学形态的重要性。最后，环境和地球化学过程和地球化学障碍，影响金属形态进行了讨论。本报告末尾简要介绍了一些其他概念和应用。
This report presents some strategies to predict metal mobility at mining sites. These strategies are based on chemical, physical, and geochemical information about metals and their interactions with the environment. An overview of conceptual models, metal sources, and relative mobility of metals under different geochemical conditions is presented, followed by a discussion of some important physical and chemical properties of metals that affect their mobility, bioavailability, and toxicity. The physical and chemical properties lead into a discussion of the importance of the chemical speciation of metals. Finally, environmental and geochemical processes and geochemical barriers that affect metal speciation are discussed. Some additional concepts and applications are briefly presented at the end of this report.
