Abstract

Mining and mineral-processing wastes have been giving a lot of concern in recent times. This paper has evaluated an integrated multidisciplinary strategy for mining wastes characterization, their possible recycling and reuse, and critical raw materials recovery. After the in situ sampling campaigns, mining wastes have been characterized and the acquired mineralogical, chemical and spectral information have been used to create a map of mining waste deposits by means of the new multispectral satellite Sentinel-2A classification. The use of Fe-Mn rich wastes in arsenic removal and phosphorus recovery from water was discussed. Furthermore, mycorrhizal-assisted phytoextraction of metals from contaminated soils classified as Class 1 to 4 by remote sensing showed a good potential for their possible recovery from biomass, and results indicated that the system was suitable for the uptake of several elements. Results are encouraging and the application of such approach can be important to develop a circular model for sustainable exploitation of mining wastes.

铁矿和锰矿废弃物分类与再利用的多学科策略研究

近年来，采矿和矿物加工废物引起了人们的广泛关注。本文评估了采矿废物特性、可能的回收和再利用以及关键原材料回收的综合多学科战略。在实地取样活动之后，对采矿废料进行了特征分析，并利用所获得的矿物学、化学和光谱资料，利用新的多光谱卫星Sentinel-2A分类，绘制了一幅采矿废料分布图。探讨了富铁锰废物在水中除砷、回收磷中的应用。此外，利用遥感技术，菌根辅助植物从1 ~ 4类污染土壤中提取金属，显示出从生物质中回收金属的良好潜力，结果表明该系统适合多种元素的吸收。结果令人鼓舞，这种方法的应用对于发展可持续利用采矿废料的循环模式是重要的。
