A conference on Mine Water Management and correction of Acid Mine Drainage (AMD), is hosted on 27 -28 September 2011 at Gallagher Estate.

AMD conference themes emphasise the need for miners to learn from observations and advances in practical long term AMD management. Mine water management should include assessment of AMD risk at pre-feasibility stages of projects, implications of climatic extremes, integration of appropriate emerging technologies and research into AMD plans and management into life-of-mine planning through to closure and relinquishment.

CSIR noted water degradation

Effects of mining on the environment includes the release of many chemical contaminants into water resources, which can cause environmental damage and threaten the health and safety of nearby communities long after mine closure.

This pollution is so persistent that, in the absence of available remedies, in many instances the contaminated sites may never be completely restored”, wrote CSIR Newsletter in August 2009.

This event aims bring together experts on environmental aspects of mining and metals from the scientific community, from government agencies, from the mining and metal industries, and from other stakeholders to share knowledge and experience and to discuss industry practices, challenges and research needs.

Approaches for prediction, prevention, treatment and control and monitoring of acid drainage, will be reviewed to assess their contribution to sustainable solutions.
