最近几年高岭土工业工艺发展惊人。美国佐治亚高岭土矿和英国康沃尔高岭土矿的经营公司,在许多领域有很大进展,如浮选和超细粒浮选等。这篇文章是讨论高梯度强磁场磁选机的推广使用。目前在佐治亚和康沃尔两矿,该磁选机广泛用于改善高岭土亮度和其它重要性能。美国高亮度高岭土生产的主要障碍是表面被氧化铁污染的锐钛矿。锐钛矿是二氧化钛的结晶形式之一,色泽比高岭土黑,磁性较弱,作为极细颗粒(通常1微米)和高岭土共存。用
In recent years, the development of kaolin industrial process amazing. The United States Georgia kaolin mine and Cornish UK kaolin mine operating companies in many areas have made great progress, such as flotation and ultrafine flotation. This article discusses the use of high-gradient, high-field magnetic separators. Currently in the two mines in Georgia and Cornwall, the magnetic separator is widely used to improve kaolin brightness and other important properties. The main obstacle to the production of high-brightness kaolin in the United States is anatase, the surface of which is contaminated with iron oxide. Anatase is one of the crystalline forms of titanium dioxide, which is colder than kaolin black and less magnetic and coexists with very fine particles (usually 1 micron) and kaolin. use
