New kaolin deposits were discovered at two different locations in Sivas, Turkey. The first deposit was located in the north of a town called Zara, towards the east of another one called Kosedag. The second deposit was in the north of Susehri, on a mountain called Igdirdag. hi this study, some physical and chemical properties of kaolin samples from those deposits were investigated after illustrating necessary geological information about the area. Mineral processing studies were also carried out to determine the suitable separation method and the related processing parameters, i.e. hydrocycloning for these two different types of kaolins.
