flotation ores

In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore. Selectivity between chalcopyrite and sphalerite, in principle, is determined by the type of copper minerals present in the ore

Flotation is a mineral separation process done in the water medium. It is based on the difference in the surface properties of the mineral and gangue. The surface of the selected mineral is made hydrophobic (water repellent) by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected as froth whereas the hydrophilic

Froth flotation has become the most important and efficient method for lithium ores processing [20]. Previous studies showed the possibility of obtaining high-lithium grade concentrates by froth flotation from Portuguese ores, as are the cases of amblygonite (Argemela deposit) and spodumene (Barroso) assaying values close to the stoichiometry of the respective minerals [18, 21]
