摘 要: 介绍了新型起泡剂730A的组成和性质，及它在某些铜矿山的应用结果。730A由α，α，4-三甲基-3-环已烯-1-甲醇、1，3，3-三甲基双环［2.2 .1］庚-2-醇、樟脑、以及C6～8醇、醚、酮按合适的比例组成。一个工业应用试验在个旧某重选-浮选厂进行，结果表明，在相同的用量下，730A所得浮选指标优于松醇油。与松醇油相比，730A所得精矿的品位提高0.51%，而铜的回收率提高3.98%。另一工业应用试验在易门某浮选厂进行，试验结果表明，使用730A不仅提高了精矿的品位和回收率，而且起泡剂用量也由53.49g/t降为35.28g/t。研究表明，浮选起泡剂在矿物浮选中具有重要的作用。

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 53.49?g/t of pine oil to 35.28g/t of 730A. It shows that flotation frothers play a very important role in mineral flotation.
