17th International Seminar on Paste and Thickened Tailings was a Great Success!

The 17th International Seminar on Paste and Thickened Tailings (Paste 2014) took place from June 10 to June 12, 2014, in Vancouver, Canada, a major hub for mining in North America. For the second year in a row, ConferenceMine (a division of InfoMine) successfully organized this leading forum on behalf of its founder, the Australian Centre for Geomechanics (ACG). Attended by 350 delegates from 17 countries, Paste 2014 was a truly international examination of tailings practices, with an emphasis on stacking with paste or filtered tailings.

Thank you to all delegates for participating. You were integral in making this year’s seminar a success.

ConferenceMine received an unprecedented 134 abstracts for Paste 2014. Out of these came sixty-one excellent papers, fifty of which were published in the Proceedings (the balance were presented as posters). The accepted papers came from fifteen countries: Australia, Canada, South Africa, the USA, the UK, Brazil, Peru, China, Chile, China, Czech Republic, Germany, Iran, Portugal and Sweden. The full book of proceedings and all sixty-one papers will be available from the InfoMine eStore.

Delegates shared advances in technology, and were able to discuss field applications and obtain feedback from practitioners working at mine sites worldwide. Delegates were also offered two days of short courses, and field trips to the Highland Valley Copper Mine and Coanda Research and Development.

This year, for the first time, a concurrent session on oil sands was included. The oil sands mines of western Canada have invested millions to research paste, drying, and stacking technologies for the fines fraction of their tailings. This has yielded advances in paste distribution, in-line flocculation, spreading, drying, reworking, harvesting, and stacking, and has advanced the science of hydraulic stacking of the sands fraction at placement rates and height advance rates that have set global precedents. Some of this valuable knowledge was shared with delegates.

The Hyatt Regency Vancouver hotel in downtown Vancouver provided an excellent venue for the many sponsors and exhibitors to display their wares. The delegates enjoyed the venue, and at the seminar dinner were treated to a stunning view of a perfect sunset from the Top of Vancouver Revolving Restaurant. Feedback from delegates has been excellent, with many expressing thanks for a well-organized seminar.

 

BACKGROUND

The Paste and Thickened Tailings Seminar, organized every year since 1999, is the leading forum for practitioners in field to meet, deliberate, and exchange knowledge and information.

The storage of tailings deposited as slurry behind embankments on ever larger and larger mines is resulting in increased sizes of embankments, water usage, land disturbance, ground and surface water pollution and risk to downstream habitats. The competition for land and water resources increases with mine size and population density. Technologies that reduce such resource usage, as well as decrease risks to the environment, are increasingly sought and applied. One group of technologies that has received increasing attention globally are those of producing paste, dried and/or filtered tailings, together with methods for the building of stacks of such tailings, reducing the requirement for dams and minimizing water usage.

The oil sands mines of western Canada have in recent years spent hundreds of millions of dollars researching and implementing paste, drying, and stacking technologies for the fines fraction of their tailings. This research and application has numerous novel aspects, including advances in paste distribution, in-line flocculation, spreading drying, reworking, harvesting, and stacking by various methods. These mines have also advanced the science of hydraulic stacking of the sands fraction at placement rates and height advance rates that have set precedents worldwide. The knowledge that has been acquired will be of value to practitioners from all over the world.
