From rough stone to a special product
Calcit obtains the raw material, marbled limestone, from two quarries. The special features of the stone are its exceptional purity and high degree of whiteness, which enable a wide range of high quality products to be manufactured for the chemical, paper and rubber industries. One quarry is located in Stahovica, in the immediate vicinity of the production plant and headquarters, while a second quarry is located about 15 kilometers from Gospic (Croatia). The raw material is then ground in two grinding stages (dry grinding and wet grinding) with the addition of various additives, into pigments, which are then used as a filler in graphic papers, newspaper printing and many other applications. The CaCO3 (= GCC ground calcium carbonate) produced by Calcit enjoys a markedly better price-performance ratio compared to the precipitated CaCO3 (= PCC precipitated calcium carbonate).
