尾矿管理战略的目的是保护环境和人类免受与尾矿有关的风险。未来矿山中低品位矿石的产量似乎不可避免地会增加，从而产生更高吨位的尾矿。2010年，全球采矿业生产了约140亿吨尾矿。因此，采矿业越来越认识到需要一个促进可持续发展的尾矿管理（包括脱水）综合框架。在本文中，我们回顾了现有的尾矿管理框架，并提出了一个改进的框架，考虑到关键的可持续发展支柱：技术，经济，环境，政策和社会方面。这一框架将能够指导采矿部门根据可持续发展概念选择其尾矿管理战略。它集成了一系列工具，用于确定在运营期间和整个矿山生命周期（LOM）中不同尾矿管理方法中固有的权衡;这些工具包括生命周期评估（LCA），净现值（NPV），层次系统模型（HSM）和决策。分析.特别是，这一建议承认尾矿管理的高度个案具体明确整合尾矿属性的物理化学表征作为第一步。在未来，该框架可以通过整合工业共生的再利用/再循环原则来扩展。(C)2015爱思唯尔有限公司版权所有。
The aim of mine tailings management strategy is to protect the environment and humans from risks associated with mine tailings. It seems inevitable that future production from lower grade ores in mines will increase, generating a higher tonnage of tailings. Approximately 14 billion tonnes of tailings were produced globally by the mining industry in 2010. The need for a comprehensive framework for mine tailings management (including dewatering) that promotes sustainable development is therefore becoming increasingly recognised by the mining industry. In this paper, we review existing frameworks for tailings management and propose an improved framework that considers key sustainable development pillars: technological, economic, environmental, policy, and social aspects. This framework will be able to guide the mining sector to choose its mine tailings management strategy based on sustainable development concepts. It incorporates a range of tools for determining trade-offs inherent in different tailings management methods during operation and throughout the Life of Mine (LOM); these include Life Cycle Assessment (LCA), Net Present Value (NPV), Hierarchy System Model (HSM), and Decision. Analysis. In particular, this proposed recognises the highly case-specific of tailings management by explicitly integrating physicochemical characterisation of tailings properties as a first step. In future, the framework could be expanded through integration of reuse/recycle principles of industrial symbiosis. (C) 2015 Elsevier Ltd. All rights reserved.
