Abstract:
     The multi-metal cassiterite sulfurizing tail concentrating method includes: graded tail throwing with combineed screw concentrating machine and screw chute; floating of the rest tail with phenyl halogenated quaternary ammonium salt and black butyl amine as collecting agent to recover sulfurized mineral of Pb, Sb, Zn, etc and sulfurized mineral oxide of Pb, Sb, Zn, etc while leaving the cassiterite and gangue inside the trough; and recovering cassiterite with sodium carbonate and carboxymethyl polyvinyl alcohol as combined gangue dispersing and inhibiting agent and through stepped floating process. Compared with traditional method, the method has concentrating grade raised by 1-3 times, comprehensive tail loss of about 10 % and 10 % raised recovering rate of Pb, Sb, Zn, Sn, etc.
