Abstract:With aniline and salicylaldehyde as main materials, a new collector for wolframite slime was synthesized. In a pulp of natural pH value, this collector can collect wolframite effectively. Its selectivity is similar to that of benzyl arsenic acid and better than that of sodium oleate. With this collector, a wolframite rough concentrate with grade 30.12% WO3 and recovery 91.50%, and a concentrate with grade 58.66% WO3 and recovery 85.00% were obtained respectively from a wolframite ore containing 4.08% WO3.
Key words: collector; wolframite; flotation
