乌斯河铅锌矿重金属淋滤特征

摘要

Leaching experiment is the common method to evaluate mine environment. The paper introduces the purpose, sam-ple handling and process of heavy metal leaching experiment. By controlling particle size and pH value, it explores the rela-tionship between the variables and the content of heavy metals, and the mechanism of transportation and conversion of heavy metals in mine environment.It provides theoretical basis for the treatment of mine environment and the optimization of min-ing.%淋滤实验是评价矿山环境危害性的最常用方法，通过模拟自然环境条件，获得被淋洗样品在自然环境中的风化淋滤特征。介绍了铅锌矿重金属淋滤实验目的、样品处理、实验过程，通过模拟淋滤实验，控制矿石样品粒径和淋滤液pH值，探究不同变量与淋出液中重金属元素质量分数之间的相互关系，探明矿山环境中重金属元素的释放转化迁移机制，为治理矿山环境、优化矿业冶炼过程提供理论依据。
