flotation: froth flotation is a standard technique for concentrating copper sulphide minerals from ores. the surfaces of the copper bearing minerals are made selectively hydrophobic with chemical action and collected in the froth, which is continually removed, from the flotation tanks.
froth flotation has become the most important and efficient method for lithium ores processing . 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].
froth flotation: this method is commonly used to concentrate sulphide ores such as galena (pbs), zinc blende (zns) etc. in this method, the metallic ore particles which are preferentially wetted by oil can be separated from gangue. in this method, the crushed ore is suspended in water and mixed with frothing agent such as pine oil, eucalyptus oil etc.
