铅锌化学选矿重金属废水的处理方案探究

Study on Treatment Scheme of Heavy Metal Wastewater by Lead and Zinc Chemical Disposal

铅锌是重要的有色金属资源,而铅锌选矿是铅锌生产的重要流程,其间会产生大量选矿废水。治理铅锌选矿废水,不仅能够消除其对水资源的污染,同时还能节约水资源,因此具有一定的经济效益和环境效益。本文首先分析了铅锌选矿的废水来源和废水特性,然后从清洁生产的视角提出处理和回收选矿废水的相关工艺。

Lead and zinc is an important non-ferrous metal resources, and lead and zinc ore dressing is an important process of lead and zinc production, during which will produce a large number of mineral processing wastewater. Governance of lead and zinc mineral processing wastewater, not only to eliminate its pollution of water resources, but also save water resources, so have a certain economic and environmental benefits. In this paper, the source and wastewater characteristics of lead and zinc beneficiation were analyzed, and then the related processes for the treatment and recovery of mineral processing wastewater were put forward from the perspective of cleaner production.
