Copper content in the flotation tailings had been changing in the same period from % at the beginning to less than % at the flotation process ending, depending on the copper ore quality and the flotation process parameters applied at that time. Characterization of the OFT In order to perform characterization of the flotation tailings ...
Bulk (CopperMoly) Flotation. Both the copper and moly sulfide ores together (bulk) float in rougher flotation cells, then cleaner column cells, and often scavenger cells. These groups of flotation cells work together to give a high total yield of the bulk ore, which is sent on to be thickened. Tailings (Gangue) Thickening / Dewatering
In 2014, a tailings dam at the Mount Polley copper and gold mine in British Columbia failed as a result of an unstable foundation, sending 24 million cubic metres of slurry into the surrounding waterways. A year later, the Samarco mine's tailings dam failed as a result of seismic activity combined with structural defects and other issues. The flood of toxic sludge was devastating.
22/05/2018 · Heron Resources has announced the award of two contracts relating to the provision of equipment supply and mining services for the reclamation of tailings for reprocessing at its wholly owned Woodlawn ZincCopper Project in New South Wales, Australia, which is currently under construction and due to commence commissioning at the end of 2018:
· This is an excerpt from International Mining's Reprocessing and Tailings Reduction Feature, written by Dan Gleeson in May 2020 edition. While tailings dam liabilities and falling water resources are affecting the ability of miners to start new mines, or expand existing ones, these issues are strengthening the case for reprocessing and retreating 'waste' sites or streams.

08/06/2021 · I n 2019, a tailings dam at the Córrego do Feijão iron ore mine near Brumadinho, Brazil, suffered a devastating failure. When the tailings dam collapsed, it released a massive mudflow that wreaked havoc on the mine site, mine staff, and nearby communities. More than 250 people lost their lives and there was a significant amount of damage done to the environment.
· Reprocessing this material is beneficial to industry for several reasons. Firstly, there are lower costs involved compared to a new mine as the ore has already been mined and milled. Secondly, tailings dams present a significant environmental problem, so reprocessing can help to reduce environmental contamination (Chen et al., 2014).
