摘　　要：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% WO 3 and recovery 91.50%, and a concentrate with grade 58.66% WO 3 and recovery 85.00% were obtained respectively from a wolframite ore containing 4.08% WO 3.With aniline and salicylaldehyde as main materials, a new collector for wolframite slime was synthesized.
