本文叙述了国内外高岭土矿床分布概况、高岭土的用途、高岭土的选矿方法和工艺。用图表形式介绍了英国尼龙顿——艾别特高岭土矿、美国某高岭土公司选厂、我国苏州高岭土矿的选矿工艺流程。作者经研究得出结论认为,国内外高岭土的选矿主要采用湿法,而干法选高岭工矿主要用于缺水地区。精制超细粉碎高岭土主要用磨剥剥片法。除去高岭土中铁钛物质的方法有:浮选法、磁选法、化学选矿法和微生物处理法。
This paper describes the distribution of kaolinite deposits at home and abroad, the use of kaolin, kaolin beneficiation methods and processes. Graphical presentation of the British Nilong Tun - Aite kaolin mine, the United States selected a kaolin company, China’s Suzhou kaolin mine beneficiation process. The study concluded that the main beneficiation of kaolin at home and abroad using wet methods, and dry-election Kaolin mining mainly for water-scarce regions. Finely ground refined kaolin abrasives peel-off method. Methods to remove iron titanium in kaolin: flotation, magnetic separation, chemical beneficiation and microbial treatment.
