The Australian Centre for Geomechanics initiated the series of international seminars on Paste and Thickened Tailings (P&TT) in 1999. Since then the seminars have become an influential and respected annual event which provides an excellent forum to bring together tailings and mine waste practitioners from around the world.

The ACG is proud to host the 21st International Seminar on Paste and Thickened Tailings in Perth, 11-13 April 2018. This seminar represents a valuable opportunity for academics, designers, practitioners, consultants and suppliers to discuss best practice, improved methods and technology, all with an emphasis on safety, efficiency and environmental impact.
