advantage of impact ore dressing vs flotation cell

Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

These are advantageous as they are less hazardous than the inorganic ones. They do not ionize in the solution, but prevent flotation forming a thin coating over the mineral particles. They are used in less amounts for depressing Talc, Graphite and Calcite. Starch and Dextrin also act as supplementary Lead depressants in Copper-Lead systems. Other appli ions include the selective depression of polymetallic sulphide ores in the processing of iron ore. 25

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
