摘要

采矿业产生大量废物,包括废石和尾矿。尾矿的处理会对环境产生影响,例如重金属会释放到地表水和地下水中。因此,充分修复采矿废物储存设施至关重要。废弃的尾矿库可能含有大量有价值的矿物,包括关键的原材料,并提供了作为次要矿产资源的机会。在本研究中,对Rautuvara尾矿库的不同尾矿进行了地球化学和矿物学表征,该尾矿库是不同矿床的最终处置场。从尾矿库的两个不同位置采集样品,进行预浓缩,并采用多种方法进行分析,包括PSA、XRD、FE-SEM、EPMA、pXRF、WD-XRF和AAS。地球化学结果表明尾矿中Cu、As、Ni和Zn的浓度显著升高。矿物学调查表明,尾矿中含有有价值的矿物,如金、钴矿和含钨金红石。最后一种可作为尾矿分类的指示矿物,也可能用于未来的矿石勘探。次生矿物学研究表明,尾矿风化程度最高的顶层在矿物颗粒表面表现出次生蚀变边缘,Fe和Mn氧化物矿物中As和Ni富集。

Geochemical and mineralogical characterization of mine tailings at the Rautuvaara mine site and aspects to environmental conditions and resource potential
Mining industry generates a significant amount of waste including waste rock and tailings. The disposal of mine tailings has environmental impacts, such as the releasing of heavy metals to surface and underground waters. Therefore, adequate rehabilitation of mining waste storage facilities is essential. Abandoned tailings ponds may contain significant amounts of valuable minerals, including critical raw materials, and offer opportunities as secondary mineral resources. In this study geochemical and mineralogical characterization were made for the diverse mine tailings of the Rautuvaara tailings pond which was the final disposal site for different ore deposits. The samples were collected from two different locations in the tailings pond, preconcentrated and analysed with several methods including PSA, XRD, FE-SEM, EPMA, pXRF, WD-XRF and AAS. The geochemical results indicate substantially elevated Cu, As, Ni and Zn concentrations in the tailings. Mineralogical investigations revealed that the tailings contain valuable minerals such as gold, cobaltite, and W-bearing rutile. The last could be used as an indicator mineral in tailings classification and possibly also in future ore exploration. The study of secondary mineralogy revealed that the most weathered top layers of the tailings show secondary alteration rims on the surfaces of mineral particles, and the enrichment of As and Ni in the Fe- and Mn-oxide minerals.
