PASTE 2018 REPORT

July 27, 2018

The 21st International Seminar on Paste and Thickened Tailings (Paste 2018) was held 11-13 April 2018, at the Rendezvous Hotel Perth Scarborough, in Perth and was attended by nearly 240 delegates, including 42 presenters and 69 sponsors and exhibitors.

The seminar sought to explore the considerations needed to raise the mining industry leaders’ awareness of how important environmental stewardship (with regard to their tailings facilities) is to long-term industry sustainability.

Over the three days of the Paste 2018 seminar, 46 presentations were made (including three posters) by presenters from 13 countries globally. The presentations covered topics in the paste and tailings arena including thickening and filtration; depositional practices and experiences; transportation; beach profiles; geotechnical aspects; backfill; operational experiences; and new developments.

The focus was on the potential benefits to be gained from adopting thickened tailings technology on mining operations. A number of operations are now retrofitting their plants and tailings storages from conventional to thickened technology. The reason for this is the increase in the mass of tailings that can be accommodated on a given footprint and, more importantly, the greater volume of water that can be recovered for re-use in the plant in arid areas.
