| 摘 要： | 鉴于我国铝土矿保有量有限,高品位铝土矿由于掠夺性开采而面临枯竭,具有高品位的高硫铝土矿将是今后氧化铝生产的主要矿物原料。而高硫铝土矿脱硫,是该类型铝土矿能否工业应用的关键。本试验采用单因素实验,研究了高硫铝土矿在浮选剂异丁黄药作为捕搜剂,松油醇为起泡剂进行高硫铝土矿反浮选除硫的工艺条件。重点考察了浮选剂用量、浮选时间、浮选矿浆浓度、pH值及矿石粒度对浮选的影响,得出了反浮选除硫的适宜工艺条件。研究表明,在适宜工艺条件下,异丁黄药浮选除硫后的尾矿中,硫含量由原矿2.08%达到15.1%,精矿中硫含量降为0.62%,达到工业生产氧化铝的要求(0.7%)。氧化铝回收率为92.3%。在弱碱性条件下,异丁黄药的捕搜性能在硫酸铜活化下有很大提高。浮选动力学研究表明,异丁黄药对硫化矿的浮选符合Langmuir的化学吸附原理。

| Abstract: | The desulfurization of high-sulfur diasporic bauxite from China with flotation process and butyl xanthate as collector was studied, and the effects of flotation time,pulp density,pH value and particle size of ores were examined.The experimental results indicate that the sulfur in bauxite was successfully decreased through foltation.The sulfur content of bauxite was lowed to 0.62% under the condition of pH value 10,the dose of flotation agent butyl xanthate 0.16kg/t,frother 20g/t,flotation time 15 minutes,pu... |
