Amorphous silica effects on copper flotation: A kinetic and …
Understanding flotation kinetics and selectivity is essential for manipulating copper flotation process involving amorphous silica. Flotation kinetics refers to the rate at which valuable mineral particles attach to air bubbles and report to the concentrate during the flotation process, and it is typically described by mathematical kinetics models [13, 14].

Effect of pH on Copper Flotation Recovery VS Mass Pull
Here, rougher flotation is most Selective at a pH of 9.5 as pH levels in the 9 to 10 range yielded 1% to 2% better recoveries. Mineralogy data also supports this and shows between 3% and 10% of the copper is present as low-grade middlings in pyrite, and further supports the benefit of floating middlings pyrite to maximize copper rougher recovery.

60 Centuries of Copper: The Flotation Process
Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.

A novel trithiocarbonate collector featuring high-temperature
The nature of copper slag flotation is unique due to the high temperature in the flotation pulp and high metallic copper content in the feed. Despite its great potential for valorizing slag, copper slag flotation remains challenging due to the deactivation of traditional dithiocarbonate (DTC) collectors (e.g., butyl xanthate) under high temperatures.
