Copper-Lead-Zinc ores. The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both.
Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been.

For the most finely crushed ore, processing workers use a method called froth flotation. This method is chiefly used with galena because the mineral is finely dispersed through the rock containing it. Flotation is the usual mineral separation or concentration process of choice. In flotation, workers use slurry reagents to float the.
