1. Introduction. The importance of flotation, as a separation process, to the economy of the whole industrial world is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical …

The great difference between E Cu and E Fe in concentrate and tailing indicates the good separation of copper and iron in the sulfuring flotation beneficiation process. The high E Cu suggests that the addition of sulfiding agent Na 2 S may increase copper recovery ( Sibanda et al., 2020 ).

The gas bubbles are used to adhere the hydrophobic particles selectively and carry them to the surface of the liquid, hence they form a froth zone where it can …
