摘 要: 介紹了新型起泡劑730A的組成和性質(zhì)，及它在某些銅礦山的應(yīng)用結(jié)果。730A由α，α，4-三甲基-3-環(huán)已烯-1-甲醇、1，3，3-三甲基雙環(huán)［2.2 .1］庚-2-醇、樟腦、以及C6～8醇、醚、酮按合適的比例組成。一個(gè)工業(yè)應(yīng)用試驗(yàn)在個(gè)舊某重選-浮選廠進(jìn)行，結(jié)果表明，在相同的用量下，730A所得浮選指標(biāo)優(yōu)于松醇油。與松醇油相比，730A所得精礦的品位提高0.51%，而銅的回收率提高3.98%。另一工業(yè)應(yīng)用試驗(yàn)在易門某浮選廠進(jìn)行，試驗(yàn)結(jié)果表明，使用730A不僅提高了精礦的品位和回收率，而且起泡劑用量也由53.49g/t降為35.28g/t。研究表明，浮選起泡劑在礦物浮選中具有重要的作用。

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.
