International Network for Acid Prevention (INAP)
Gilles Tremblay is the Technical Manager of the International Network for Acid Prevention (INAP), an organization of international mining companies that seeks the prevention of mine-impacted waters through collaborative research, information transfer and networking in support of responsible mineral development. Mr. Tremblay also coordinates activities jointly with the Global Alliance, which has organizations working on acid prevention in Australia, Canada, Europe, South Africa, South America and USA. Prior to joining INAP Gilles worked for the Government of Canada for more than 33 years coordinating large multi-party R&D consortia related to environmental issues affecting the mining industry (e.g. MEND and NOAMI).
Understanding Acid Mine Drainage / Acid Rock Drainage and the implications for rehabilitation and closure
Rehabilitation is an important part of mine closure and our understanding and implementation of rehabilitation practices has developed significantly over the last three decades. Most mining companies now aim to leave a post-mining legacy with a sustainable land-use, with rehabilitation playing a key role. However, mine closure is a complex and multi-disciplinary process which presents a diverse range of major risks. When sulphides are present in the ore body, the formation of acid and metalliferous drainage (AMD) or acid rock drainage (ARD) can result and this is regarded as the main environmental concern of the mining and minerals industry today. Unmitigated, ARD/AMD can result in water quality impacts that could well be the industry’s most significant financial and credibility risk. The long term impact and treatment cost of AMD/ARD can delay and prevent mine closure and subsequent relinquishment. It has also historically left a global legacy of abandoned mines which still require attention. The aim of this short course is to help attendees develop a better understanding of the fundamentals of AMD/ARD generation processes and management options through to closure. The topics will be presented in an interactive manner, using real case studies from around the world. The course, could be regarded as introductory for some and as a refresher for others, will be ideal for mining industry environmental and mine planning practitioners, mining regulators and post graduate students.
This short course is coordinated by Mr. Gilles Tremblay, Technical Manager of the International Network for Acid Prevention (INAP) and will include presentations by leading AMD/ARD specialists from Australia and Internationally. Discussion topics will include:
