常规浮选的主要限制是回收细颗粒。但是 ,天然产状为细颗粒的高岭土的分选已有 40多年的工业实践了。高岭土是制造白色颜料的有用矿物。高岭土的浮选目的是除去有颜色的矿物 ,提高它的白度。高岭土的选矿方法最初是载体浮选 ,以后又开发出无载体浮选工艺。高岭土浮选所用捕收剂主要是脂肪酸类 ,最近成功地用羟肟酸作捕收剂。本文的目的是叙述高岭土浮选的历史进展和所用的药剂制度
The main limitation of conventional flotation is the recovery of fine particles. However, the natural production of fine-grained kaolin has more than 40 years of industrial practice. Kaolin is a useful mineral for making white pigments. The purpose of kaolinite flotation is to remove colored minerals and improve its whiteness. Kaolin method of beneficiation was initially carrier flotation, and later developed a carrier-free flotation process. The main collectors used in kaolin flotation are fatty acids, which have been recently successfully used as collectors. The purpose of this paper is to describe the history of kaolinite flotation and the system of agents used
