Obtaining Fillers Based on Limestone from Deposit Brijeg-Ulcinj for Applications in Various Industries

Abstract

Paper presents results of investigations of the possibility of using “Brijeg”-Ulcinj limestone as filler in various industries. Micronization, granulometric composition, oil and water absorption and degree of whiteness were investigated, and chemical and thermal analyses were performed. Physico-chemical properties of this sample classify it among high quality carbonate raw materials with high CaCO3 content of 98.21%, with low contents of MgCO3 0.88 % and SiO2 0.16 %. Its quality satisfies requirements of standards on using of calcium carbonate as filler in next industries: paints and coatings; rubber and PVC; glass; foundry ; sugar industry production of mineral fertilizers and metallurgy.
