本文叙述了自1930年以来,高岭土选矿工艺所取得的重大进展。主要是:(1) 分散和絮凝药剂研究的进展;(2) 用连续淘浆机在矿山就地把高岭土制浆;(3) 用耙式分级机和水力旋流器连续除砂;(4)从矿山到选厂用管道输送高岭土矿浆,以降低成本;(5) 采用连续式离心机(每台每小时处理量为25吨)把颗粒分成粗、中、细三种粒级,大大提高了生产率;(6) 化学浸滤除铁以改善亮度和色泽;(7)
This article describes the major advances made in kaolin beneficiation since 1930. Mainly: (1) the progress of research on dispersing and flocculating agents; (2) pulping kaolin in situ with a continuous auater; (3) continuous desilting with a rake grader and a hydrocyclone; (4) ) From the mine to the selected plant pipeline transport kaolin pulp, in order to reduce costs; (5) using continuous centrifuge (each processing capacity of 25 tons per hour) to the particles into coarse, medium and fine three kinds of particle size, greatly increased (6) chemical leaching iron to improve brightness and color; (7)
