基于文献回顾的有色金属冶炼废渣的特征、资源化途径及其安全利用评价

Characteristic,resource approaches and safety utilization assessment of non-ferrous metal smelting slags:A literature review

冶炼废渣作为冶炼过程中产生的工业副产物,由于其缺乏安全、合理的防护和管理措施可能导致环境问题。通过全面分析近年来发表的相关文献,本文对有色金属冶炼废渣的特性、资源化利用途径及安全利用评价等方面的最新研究进展进行了介绍。研究结果表明,不同的原生精矿、冶炼条件和冶炼类型决定了冶炼废渣的化学和矿物学特征。此外,冶炼废渣在各种资源化利用中表现出极高的灵活性,不仅可以用于金属回收和建筑材料,还可以作为农业肥料和修复剂。同时,本文强调了在各种利用情景下对废渣进行安全性评估的重要性,以降低其潜在环境风险。此外,本文还强调了未来的研究方向,包括建立一种综合且量化的土渣混合体中重金属环境风险评价方法,以及探索更多创新的冶炼废渣资源化利用方法。综上所述,本文对于推动冶炼废渣在环境保护和资源可持续利用方面的研究有重要意义。

As an industrial byproduct of smelter operations,smelting slag has brought certain environmental issues including without taking safety precautions or using appropriate management.Through a thorough analysis of the literature published in the last years,the latest research progress on the characteristics,resource utilization pathways,and safety utilization evaluation of non-ferrous metal smelting slag was introduced in this work.Key findings indicate that different ore concentrate materials,smelting conditions and types determine chemical and mineralogical characteristics of smelting slag.Moreover,smelting slag exhibits extremely high flexibility in various applications,not only as metal recovery and construction materials,but also as agricultural fertilizers and remediation agents.At the same time,the importance of conducting strict safety assessments under various utilization scenarios to mitigate its potential environmental risks is emphasized.In addition,this article also emphasizes the direction of future research,including creating a comprehensive and quantized environmental risk assessment method of heavy metals in soil-slag mixtures,as well as exploring more innovative utilization methods of smelting slag.Overall,this review is significant for promoting research on the use of smelting slag in environmental protection and sustainable resource utilization.
