摘要： 以十二胺为捕收剂,通过单矿物浮选试验对异极矿的可浮性及正辛醇对异极矿可浮性的影响进行了初步研究.结果表明,当pH值在10~11范围内,适量的十二胺对未经活化的异极矿具较好的捕收性;正辛醇对异极矿不具有捕收性.正辛醇能够强化十二胺阳离子在异极矿表面的吸附,降低十二胺的浮选起始浓度;当正辛醇以25%的物质的量比取代十二胺组成胺醇复合捕收剂时,使用复合捕收剂可获得与使用十二胺相同的浮选效果.

Abstract: The monomineral flotation test which for investigating the flotability of hemimorphite and the influence of n-octanol on the flotability of hemimorphite were conducted using dodecylamine (DDA) as collector. The results showed that the unactivated hemimorphite can be collected well by appropriate dosage of DDA while the pH of pulp located in 10 to 11. Hemimorphite can't be collected by n-octanol. Adsorption of DDA's cation on hemimorphite's surface and the minimum activated concentration of DDA were downgraded by n-octanol. The same flotation effect was achieved when using the combination collector which 25% amount of substance proportion DDA was replaced by n-octanol, compared with using DDA alone did.
