Abstract

Based on the available literature this paper evaluates the environmental effects of copper mine tailings (CMT) when used as structural fill material in various geotechnical applications. Leaching of heavy metals from the CMT is considered as the vital factor hindering its wider acceptability among researchers and engineers. Therefore, apart from physical and chemical characteristics, due consideration was given to assess the leachability of CMT when used as structural fill in various geotechnical applications like subgrade, embankment, fill and reclamation. From the literature review, it was found that CMT seems to be satisfying the criteria meant for structural fill. Leachability test results show that only a very few elements concentration exceeded the limits in un-stabilized form. Stabilized CMT performed better by bringing down the concentration well below the permissible limits in all the application types. This encourages the utilization of CMT in structural fills and shows that environmental impacts are within the limits prescribed in standards.

铜尾矿在各种岩土工程应用中的环境影响综述

在现有文献的基础上，对铜尾矿作为结构填料在各种岩土工程应用中的环境影响进行了评价。从CMT中重金属的浸出被认为是阻碍其被研究人员和工程师广泛接受的重要因素。因此，除了物理和化学特性外，我们还充分考虑了CMT作为结构填料在各种岩土工程应用(如路基、路堤、填方和填海)中的淋溶性。从文献综述中，我们发现CMT似乎满足了结构填充的标准。浸出性试验结果表明，只有极少数元素以不稳定形式超标。在所有应用类型中，稳定的CMT通过将浓度降低到远低于允许的限度而表现更好。这鼓励在结构填充物中使用CMT，并表明环境影响在标准规定的范围内。

期刊介绍： Waste and Resource Management publishes original research and practice papers on all civil engineering and construction related aspects of the resource management cycle, from the minimization of waste, through the re-use and recycling, to the management and disposal of residual wastes. Associated legislation, standards, socio-economic considerations and links with sustainable consumption and production are included. The range of subjects covered encompasses, but is not restricted to, strategies for reducing construction waste through better design, improved recovery and re-use, more efficient resource management, the performance of materials recovered from wastes, and, the procurement, planning, design, construction, operation and logistics of waste and resource management facilities.
