ACG Is the Future Filtered? Paste and Thickened Tailings Short Course

20 September 2021 | The Esplanade Hotel Fremantle, Western Australia


Drawing on experiences from operational filtered tailings facilities, the short course will discuss available technologies, appropriate test programmes to determine relevant design parameters, operational challenges, and cost comparisons.
This short course was held in South Africa in May 2019, attended by 114 people.  We look forward to presenting the updated course alongside the 24th International Conference on Paste, Thickened and Filtered Tailings.
This course will be held as a traditional physical event in Perth, Western Australia, COVID-19 permitting, as well as an online event.
