摘　　要：在生产过程中,由于石灰等pH值调整剂的加入,引入了成垢离子,导致搅拌桶、浮选柱以及管道等设备结垢严重。阻垢剂通过与成垢阳离子(Ca^2+,Mg^2+)的相互作用,能较好地抑制垢的生成,其成果已广泛应用于水处理及工业管道输送领域。本文尝试将阻垢剂应用于浮选中。选用黄铁矿作为浮选矿物,通过单矿物浮选试验,以红外光谱、捕收剂的吸附量作为表征,发现阻垢剂的加入对黄铁矿的浮选存在抑制作用。In the productive process, the addition of the lime and other phmodifier brings in the scaling ions, causing the serious scaling of agitation vat,flotation column, pipeline and otherfl otation equipment. Due to the interaction between the scale inhibitor andthe scaling positive ions, such as calcium ion and magnesium ion, scale inhibitors can restrain the scaling generation and have been widely applied in industry, such as water treatment and pipeline transportation. Consequently, scale inhibitor can be tentatively used in flotation. The article chooses pyrite as flotation target and concludes the inhibitory effect the scale inhibitor has on pyrite, based on the single mineral flotation tests and the absorbed amount of the pyrite.
