Water in Mining Conference Proceedings 2009

This 2009 conference addressed two technical issues of the time, water and energy. The proceedings include papers covering areas such as treatment technologies and treatment practices, water efficiency and quality, water accounting and auditing, as well as probabilistic forecasting and systems modelling and a number of papers from operating mines. Management of groundwater was an important theme for the conference. This is supported by a number of papers dealing with groundwater management in different regions around Australia. A welcome elaboration of this conference, compared to the previous water in mining events, are the papers dealing with minerals processing; improving the flow sheet and understanding of emergent phenomena arise in several papers.
