- Flotation Process Mining Of Zinc
As is well-known, the presence of metal ions in slurry affects the flotation behavior of minerals. The Pb 2+ plays a regulatory (activation or inhibition) role in the flotation of sulfide and oxidized minerals, so it has been added to the process either as a flotation agent or as an unavoidable ion that interference with flotation. For example, …

On the other hand, the valorization of minerals requires ores to be viewed as polymetallic resources. Therefore, new process design is a crucial aspect for improving circularity (Cisternas et al., 2021, De los Rios and Charnley, 2017). As indicated above, the flotation process is a method that is used extensively in the mining industry.
