This paper presents the latest overview of the environmental impact of wastes from the non-ferrous metallurgical industry. Ashes, slags and dusts - by-products from mining and metal processing - are sources of toxic metals, such as Pb, Cd, Hg, As, Al, as well as particulate matter. Physical, chemical and biological processes transform industrial wastes and cause water, soil and air pollution. Improperly protected heaps are subject to wind erosion and rain water leaching. Heavy metals and particulate matter are transported over long distances, contaminating the soil, living areas, watercourses, while in combination with mist they create smog. Water erosion releases heavy metals, which are leached into groundwater or surface runoff. This paper focuses on the range of pollution emissions from non-ferrous metallurgy wastes, hazards, mechanisms of their formation and fallouts, on the current state of technology and technological risk reduction solutions. The impact of pollution on human health and the biosphere, and methods of waste reduction in this industry sector are also presented. A sustainable and modern mining industry is the first step to cleaner production.
本论文呈现了有色金属冶金工业废物对环境影响的最新概述。矿冶加工产生的灰渣和粉尘是 Pb、Cd、Hg、As、Al 等有毒金属以及颗粒物的来源。物理、化学和生物过程会改变工业废物的形态,造成水、土、空气污染。如果没有妥善防护,废渣堆会受到风蚀和雨水淋溶的影响。重金属和颗粒物会被长距离传输,污染土壤、生活区、水道,与雾结合形成烟雾。水蚀会释放重金属,这些重金属会被淋滤到地下水或地表径流中。本文重点关注有色金属冶金废物的污染排放范围、危害、形成机制和后果,以及当前的技术状况和减少技术风险的解决方案。本文还介绍了污染对人类健康和生物圈的影响,以及该行业废物减排的方法。可持续和现代化的采矿业是实现清洁生产的第一步。
