Abstract: The components and properties of a new flotatio n frother, 730A, are presented. At the same time, the experimental results of 730A in the flotation of some copper ores are reported here. The flotation frother 730A is a mixture of α,α,4-trimethyl-3cyclohexene-1-methanol, 1,7,7- trimethyl-bicyclo[2.2.1]heptan-2-ol, cineol, and alcohol, ethers, ketone of C6~8 at a suitable ratio. One industry-scale flotation test was carried out in a gravity-flotation plant in Gejiu. The flotation indexes obtained by the frother 730A are better than that by pine oil at the same dosage. As using 730A frother, the concentrate grade increased 0.51% and the recovery of Cu increased 3.98% compared with the flotation indexes obtained by using pine oil asfrother. The other industry-scale flotation test was carried out in a flotation plant in Yimen. The results indicated that 730A not only increased the concentrate grade and recovery , but also decreased the frother dosage from 53.49g/t of pine oil to 35.28g/t of 730A. It shows that flotation frothers play a very important role in mineral flotation.

浮选是矿物加工的主要方法之一。 浮选药剂是决定浮选效果的重要因素, 但近年来, 对浮选药剂进行研究时, 往往仅注重于捕收剂和调整剂的开发及机理研究
[1,2,3,4]。 浮选过程可分为3步: ① 化学药剂选择性改变矿物表面的疏水性或亲水性; ② 疏水性颗粒与气泡接触并粘附; ③ 可浮性矿物与不可浮性矿物分离。 起泡剂在后两步中起着重要作用
