This thesis mainly reviews the researches of flotation reagent for fine wolframite in internal and external.
本文主要综述国内外黑钨细泥浮选药剂研究情况，重点阐述了黑钨细泥浮选捕收剂的研究进展。
Nowadays, gravity concentration is used to recover fine wolframite, but the recovery of wolframite is lower than 45%.
现阶段，我国细粒级黑钨矿的回收主要采用重选法，其中钨的回收率一般在45%以下，损失率较大。
Chelating agents combined with neutral oil may be used as effective collector for fine wolframite. The selectivity of flotation is much better than that of sodium oleate.
螯合剂中性油可以作为细粒黑钨矿的有效捕收剂，其选择性远比油酸钠好。
