摘要
为提升萤石矿浮选效率,合成了(E)-N-(2-羟乙基)十八碳-9-烯酰胺,并将其与油酸钠复配成新型捕收剂CYHS-7。分别以CYHS-7和油酸钠为捕收剂,进行萤石浮选实验研究。结果表明,浮选适宜的pH值为9,CYHS-7和油酸钠闭路浮选的适宜用量分别为175和350 g/t;在实验室规模的闭路浮选实验中,在CYHS-7用量仅为油酸钠用量一半的条件下,萤石回收率提高了9.15百分点。
To enhance flotation efficiency of fluorite ore,(E)⁃N⁃(2⁃hydroxyethyl)octadec⁃9⁃enamide was synthesized and then compounded with sodium oleate to prepare a novel collector CYHS⁃7.Then,an experiment on flotation of fluorite with CYHS⁃7 and sodium oleate as collectors was conducted,and the results demonstrate that an appropriate pH for flotation process is at 9,and the optimal dosages of CYHS⁃7 and sodium oleate in a closed⁃circuit test are 175 g/t and 350 g/t respectively.In a laboratory flotation test,the recovery of fluorite was increased by 9.15 percentage points with the dosage of CYHS⁃7 at half that of sodium oleate.
