Conference schedule

The conference will be spread over 3 weeks in November 2020,
with 2 sessions per week and 3-4 presentations per session.

• 10 November-10h00 – 12h30: Sustainable treatment technologies
• 12 November-10h00 – 12h30: Value recovery
• 17 November-10h00 – 12h00:  Mine closure practices and legislation
• 19 November-10h00 – 12h30: Case studies
• 24 November-10h00 – 12h40: Student session

Type of Event

At this point in time, the event is planned as a hybrid conference with international participation, which will allow for contact and online attendance and presentation. We are still in Stage 1 Lock down in South Africa as a result of COVID-19. We will monitor the situation, and if it appears that the effects of the pandemic are still such as to pose a threat to the health and safety of delegates, or restrictions are lifted to allow for more contact participation and international travel, the event delivery method will be adjusted accordingly.

Please submit your abstracts and papers as these will be peer reviewed and published for all contact and hybrid/online conferences.

About the Online Conference

The University of the Witwatersrand through the DSI/NRF SARChI research chair in Hydrometallurgy and Sustainable Development in collaboration with Mintek and the Southern African Institute of Mining and Metallurgy (SAIMM) will be hosting a conference on mine impacted water including acid mine drainage (AMD). With a theme of “From research to implementation: considering mine impacted water as a resource”, the conference which will run over a period of three weeks in the month of November this year, will provide excellent opportunities for industry, researchers and other stakeholders from across the globe to share unbiased expertise and advocacy with respect to the legacy and sustainable solutions related to mining and mine impacted water. The workshop, with its extensive program will also offer notable keynote speakers, student sessions and panel discussions, all with the purpose of giving a unique view into novel solutions and industry progression on the issue of mine impacted water.
