“…The trend of adsorption appears familiar with flotation, which proves that the adsorption of the surfactant on the mineral surface plays an essential role in froth flotation. The result is consistent with the early study using sodium oleate as the (11). Surface species distribution of cassiterite (12)(13)(14) and distribution of oleate species as a function of pH are shown in Fig.…”

The interaction of cassiterite with sodium oleate was investigated by flotation, adsorption, Zeta potential measurements, and infrared spectrum studies. Both adsorption and flotation recovery achieved a maximum at pH 7.8. The maximum recovery of cassiterite was 91%. The tendency of adsorption was in good agreement with that of flotation. Free energy of adsorption was calculated to be À8.36 kcal/mol. The isoelectric point (IEP) of cassiterite appeared at pH 5, and showed an acid shift in the presence of sodium oleate. This shift in IEP was attributed to chemisorption of oleate on cassiterite. The infrared spectrum studies revealed that there was a new compound formed on the surface of cassiterite after interacting with sodium oleate. The results conformed that the adsorption of sodium oleate on the cassiterite surface was due to chemisorption. Based on the experiment results, the adsorption of sodium oleate on the cassiterite surface was caused by the exchanging of ions chemically at the cassiterite-oleate interface.

“…The lack of an IEP in this range means that silicate minerals will be electrostatically attracted to a cationic collector and it may not be possible to selectively concentrate muscovite from these minerals. Examples of quartz and feldspar flotation with cationic amine collectors indicate that these minerals must be effectively depressed for selective flotation to occur [54][55][56][57][58][59][60]. Calcium lignin sulfonate (Goulac), a silicate depressant, is commonly used in muscovite flotation [61,62].…”

“…The mixed collectors were composed of cationic alkyltrimethylene diamine and anionic petroleum sulfonate. A similar reagent scheme consisting of a combined cationic-anionic collector, N-tallow-1,3-propylene diamine/dioleate, was also applied successfully on feldspar ores [10,11]. Several other studies without involving fluoride ions are limited to either single mineral flotation or artificial mixtures [12][13][14][15].…”
