ICARD-IMWA 2015 is organized to provide an international forum where mining professionals, operators, researchers and suppliers can meet to exchange, interact, analyze and discuss experiences and recent innovations in the area of sound and responsible mine water and effluent management. These proceedings contain 220 abstracts of papers and posters written by authors from 24 countries. The main topics addressed by the abstracts included in these proceedings are: Geomicrobiology, biogeochemical cycles and biomining; Applied mineralogy and geoenvironmental units; Prediction of drainage flow; Prediction of drainage chemistry; Mine water and drainage collection and treatment; Cover design and performance; Scaling from laboratory to field studies; Reliable mine waste management; Reliable mine water operation; Mine dewatering; Mine water management for closure; Mine water geochemistry and Pit lakes.
ICARD-IMWA 2018 is organized to provide an international forum where mining professionals, operators, researchers and suppliers can meet to exchange, interact, analyze and discuss experiences and recent innovations in the area of sound and responsible mine water and effluent management. The majority of the papers included in the proceedings will deal with mitigation, remediation, and responsible mine water management. The conference aims to be a platform for exchanging ideas and experience from mining operations to remediation of abandoned mine sites in various climatic and cultural conditions.
This document provides oil sands mining operators with guidelines for the audit and assessment process consistent with the requirements set out in the Performance Management documents from COSIA. There is a requirement for a 5-year audit and assessment by an independent team of audit/assessors. Through this process, the audit and assessment team will: 1. Assess the reasonableness of the relevant plans and reports. 2. Provide an opinion as to whether the mine closure plan is realistic and the progressive management of FFT is on track to the desired closure outcome.
Quote from main page: A Guide to the Management of Tailings Facilities (the Tailings Guide) is designed to be applied by MAC members and non-MAC members alike, anywhere in the world. The Tailings Guide, first released in 1998, provides guidance on responsible tailings management, helps companies develop and implement site-specific tailings management systems, and improves consistency of application of engineering and management principles to tailings management.
Planning, operating, monitoring and closing a tailings storage facility (TSF) can present many challenges, especially in dynamic mining environments where site conditions vary spatially and with time. However, big impacts can be made at relatively small cost once the tailings management system, design and performance are well defined and understood. This paper presents various examples of initiatives aimed at achieving the design intent that have been adopted by Rio Tinto Iron Ore, which also reduce risks and improve tailings management performance. Examples presented include development and communication of short-term, long-term and life-of-facility deposition plans, implementation of simple deposition management tools, monitoring and managing slurry density, development and continual oversight of water balance models, and sound investment in water management infrastructure extending to safe performance in emergency situations. Regular governance was also implemented to provide assurance that these controls remain effective.
There are growing expectations of mining companies to operate in a more sustainable manner, with a strong business case for improving waste management and reducing environmental impacts. As the stewardship of tailings come under increasing scrutiny, decision-makers are urged to adopt a robust approach to the selection of a tailings management strategy that encompasses design for closure, and leading practices to lower the risk of catastrophic dam failures, optimise the use of resources, and mitigate environmental impacts on climate change. An integrated analysis, considering economic, environmental, social, and risk aspects of the operation can therefore provide decision-makers with balanced information to ensure the right projects proceed with an optimal business case so that the most cost-effective solution, that does not externalise costs, can be selected. However, literature review revealed that fundamental shortcomings exist within traditional evaluation approaches used for economic comparisons. This paper reports on life cycle cost analyses conducted for comparing various tailings management options under different scenarios. A conceptual case study for the disposal of gold tailings in Western Australia as a slurry, as thickened, or as filtered tailings, was considered. This was done for examining the extent to which potentially hidden costs impact on the total cost of a project. It is suggested that the proposed approach will lead to selection of a tailings management alternative that ensures sound economic, environmental, and social performance is achieved.
In considering the critical aspects required to improve tailings dam safety, the following subjects are addressed in this Bulletin: Corporate and Management Commitment, Education and training of company staff, Critical aspects relating to the design of a tailings dam, Critical aspects to be considered when designing for and implementing the final closure of a tailings dam, Risk management, The essential need for regular external audits and Some notes on the positive role that is played by industry regulators. The conclusion reached in the document is that diligent attention to these critical aspects will result in improved awareness and a lowering of safety incidences for tailings dams.
This Bulletin is devoted to the development and the implementation of a dam safety management system for dams in the operational phase of their life cycle. It outlines the general structure of a systems approach to safety management, and strives to develop a system that can address all the interdependencies, and encompass all the arrangements necessary to ensure proper dam safety management. This bulletin is intended to be helpful in developing, implementing, reviewing and improving the management of dam safety at all organizational levels.
This bulletin is intended primarily for the use of the Regulatory Agencies responsible for the safety of tailings dams, both structurally and environmentally. However, it is also intended to assist the mine operator in understanding the measures that must be adopted to ensure that his tailings dam is safe, both during operation and after rehabilitation. Finally, it should also benefit those individuals or organizations involved in the design, construction, operation, and rehabilitation of tailings dams.
