摘要
对龙南稀土尾矿的分选产品之一──高岭土精矿进行了实验研究，用其生产工业硫酸铝，确定了工艺路线并得出了最佳工艺条件，对反应过程中出现的问题提出了解决办法。在实验室制出了符合化工部ＨＧ－２２２５－９１标准的工业硫酸铝样品。
The technology of producing industrial aluminium sulfate from Kaolin minerals which was separated from Longnan rare earths tailing has been studied. A technological production line was established and the best conditions for reaction were defined. Problems in processing were solved and discussed.A sample of industrial aluminium sulfate in laboratory met the standard HG 2225-91 was obtained
