Among several neutral oils, transformer oil shows the best agglomeration effect. For the complex tailings, in which over 90% of molybdenum distributed in the range of -0.038 mm, the optimal dosage of transformer oil and frother was about 12 kg/t and 0.5 kg/t respectively, and the least agitation time and rate should above 3 min and 400 r/min, respectively.

结果表明，在众多中性油中，变压器油表现出了较好的油团聚浮选效果，对于钼金属分布率高于90%的-0.038mm粒级的浮选尾矿，其合适用量需达到12kg/t左右，与之配合的起泡剂用量在0.5kg/t左右，油团聚时间及搅拌强度分别需达到3min和400r/min以上。

As the foaming agent is the continued increase in frother dosage of 400g / t, the gas holdup appears the phenomenon of axial turning point was not obvious, the axial distribution of gas holdup tends to uniform.

随着起泡剂用量的继续增加，在起泡剂用量为400g/t时，气含率出现轴向拐点现象不明显，气含率轴向分布趋于均匀。
