Bubbles to batteries: A review of froth flotation for …
Therefore, the present paper for the first time scans the fundamental and applied challenges and opportunities of using froth flotation as a practical solution for recycling batteries not only targeting graphite but also selectively separation critical elements. Another focus of this work is given to the pretreatment methods which are extremely ...
Flotation Froth
Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). ... Amine collectors are also effective at floating cyanide-depressed pyrite in alkaline solutions, although the flotation rate is slow (Ramsay, 1978; Broekman et al., 1987).
Sustainable utilization of copper post-flotation waste in …
The copper ore post-flotation tailings produced by froth flotation are a mixture of water, ground rocks, and chemical reagents and represent 95–99% of crushed ores; this means that for each ton of copper obtained through froth flotation, 151 tons of tailings are generated. ... New technological solutions, taking into account the chemical ...

Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
