The adsorption of Sulphonated polyacrylamide(PAMS)on ilmenite and feldspar fromaqueous solution and the floeculation of minerals by PAMS have been studied.The researchresults reveal that the strong adsorption of PAMS on ilmenite results in its strongflocculation and the weak adsorption of PAMS on feldspar causes its dispersion to be morestable.The mechanism of PAMS bonding is discussed in terms of co-ordination and H-bonding interaction respectively in the light of molecular orbit.The co-ordination between—So_3~- on PAMS chain and sites of Ti~(4+) or Fe~(2+) on ilmenite was testified by electron spec-troscopy(PHI550ESCA/AES).Consequently new technology“Bulk flocculation-magneticsepa-ration-ultrasonic deflocculation-magnetic separation”for fine ilmenite/titano-magnetite/feld-spar system has been successfully developed. 相似文献
