【摘要】：以環(huán)氧氯丙烷、十二烷基二甲基叔胺及丁二酸為原料合成新型Gemini含酯基陽離子表面活性劑M-302B。以M-302B為捕收劑對石英和磁鐵礦純礦物進(jìn)行浮選試驗(yàn)表明M-302B可用于石英和磁鐵礦的浮選分離。以M-302B為捕收劑對酒鋼選礦廠焙燒—磁選后的精礦進(jìn)行浮選試驗(yàn),結(jié)果表明,在礦漿p H=7、溫度為25℃、苛性淀粉用量為400 g/t、M-302B用量為400 g/t條件下,可得到精礦鐵品位為60.24%、回收率為82.19%,選礦效率為31.13%的指標(biāo)。M-302B與十二胺浮選性能對比試驗(yàn)表明,相較于十二胺,M-302B捕收能力強(qiáng)、耐低溫且產(chǎn)生泡沫易被消除。ζ電位測試和紅外光譜分析表明,M-302B在石英表面的吸附機(jī)理主要為物理吸附和氫鍵作用。量子化學(xué)計(jì)算表明M-302B活性高于十二胺。
[Abstract]:A novel Gemini ester containing cationic surfactant M-302B was synthesized from epichlorohydrin, dodecyl dimethyl tertiary amine and succinic acid. The flotation experiments of quartz and magnetite with M-302B as collector show that M-302B can be used for flotation separation of quartz and magnetite. Using M-302B as collector, the flotation test of the concentrate after roasting and magnetic separation in Jiugang concentrator was carried out. The results showed that under the conditions of pulp pH 7, temperature 25 鈩，
