Tailings Dewatering Technologies 

Speaker: Ms. Rachel Jansen, Senior Process Engineer at Paterson & Cooke
About the Talk:
The 2019 failure of the Brumadinho dam in Brazil triggered an industry-wide demand for more transparency, accountability and safeguarding of people and environments from the consequences of a tailings facility failure.
In response, the Global Tailings Review published a standard in August 2020 which includes requiring consideration of alternative options to conventional tailings storage facilities, such as in-pit storage and underground tailings placement, and the application of technologies to minimize the volume of tailings and water placed in external tailings facilities. Tailings dewatering technologies, such as thickening and filtration, provide solutions to minimize stored water volumes.
