It was recently also illustrated that NB generation in the presence of conventional flotation reagents, besides improvement in the flotation recovery, could reduce the overall chemical consumption through the process [Citation 15] (Table 1).However, these investigations mostly assessed NB flotation's effect on a narrow size range (ultrafine or coarse range).

Generation Of Wastes In Copper Froth Flotation
May 01, 2015 On the other hand, a high copper content also signals that this valuable metal is lost in the process and flotation must be optimized or an extremely economic additional copper recovery and "waste" treatment method be established for PCB froth. Bioleaching was seen to be a possible option for copper separation and waste treatment. 3.2.

Enrichment implication of froth flotation kinetics in the separation
The e-waste printed circuit boards (PCBs) are rich in metal content and processing these wastes for extracting the metal values and removing the non-metallic constituents is a prospective proposition. Froth flotation methodology was observed to be a promising technique for rejecting plastics from the comminution product.

Copper Ore
The most effective method of isolating the Cu minerals is froth flotation. This process causes small Cu–Fe–S and Cu–S mineral particles to become attached to air bubbles rising through a finely ground ore slurry (Fig. 1.5).Selectivity of flotation is created by using chemical reagents (collectors) that make the Cu minerals water-repellent while leaving …

Flotation generally consists of three stages: rougher, scavenger, and cleaner, each including a certain number of flotation steps. In the case of flotation without recirculation, the treatment of the material generates three products: a concentrate (final froth), a waste (final tail), and middlings (cleaning tails plus scavenging froth).
