Over the past two decades there have been significant advances in our understanding of the causes and potential effects of Acid and Metalliferous Drainage (AMD) from mining and mineral processing operations. Early recognition and management of AMD is necessary to produce a significantly better environmental outcome at mine closure.However, AMD remains a challenging subject that continues to be underestimated and long term management costs are often not correctly factored into company balance sheets.

This Webinar presents an overview of the occurrence and potential impacts of AMD and is based upon twenty years’ of experience at mining operations both in Australia and overseas. Several case studies are integrated throughout the technical parts of the presented paper to provide relevant context and to ‘bring the geochemistry and concepts to life’.

The presentation includes information on methods used to predict and prevent AMD, although it is recognised that in some cases AMD can only be mitigated. Additional sources of useful information on AMD are also provided for further reading.

What will you get out of attending this free webinar?

1. An understanding of why AMD presents a huge challenge to the mining and mineral processing industry around the world.

2. An improved understanding of early recognition and management techniques for AMD.

3. An appreciation of methods that can be used to predict and prevent AMD.

4. Examples of case studies at mining operations and practical solutions.

5. Provision of additional sources of useful information on AMD for further reading.
