Abstract: On the basis of other people's researches, the basic physical andsurface characters of ultrafine ground calcium carbonate are summarizedThe technical parameters of ground calcium carbonate for paper industryare also given.An advanced process is introduced, including the pretreat-ment of the selected minerals, the special purpose, conditions and processin this wet grinding method. The present situation, application, and alsothe future directions of development of ground calcium carbonate, in paper industry, are indicated. In this process, a pretreatment of ground cal.cium carbonate mineral origin is taken into account to obtain a slurry withclose grain size distribution, which is more suitable for paper making. Anda mature vertical mill system with large chamber volume, small grindingmedia, highly effective separating system, well-resistant materials and anautomatic control panel, is recommended.
