Vilela, V & Salvate, M 2020, 'High production for filtered tailings and treated water', in H Quelopana (ed.), Paste 2020: 23rd International Conference on Paste, Thickened and Filtered Tailings, Gecamin Publications, Santiago, https://doi.org/10.36487/ACG_repo/2052_09 (https://papers.acg.uwa.edu.au/p/2052_09_Salvate/) Abstract: This study aims to analyses the use of high-pressure filter presses in the dewatering of slurry resulting from mineral processing, especially iron ore mining tailings and slimes. The current practice problems of deposition of fines in tailing dams were analyzed, as well as the new challenges faced by the sector in relation to water scarcity and energy efficiency. Are listed technological differentials implemented in Matec filter presses and analyzed the benefits in application of this technology, such as higher water recovery, reduce of environmental impacts and reduce of operating costs for handling and disposal of waste. Lastly, we analyze the filtration tests performed on iron ore tailings and slimes and a case study.
