Geological characteristics of the limestone deposit "Dobrilovići" - Loznica and its preparation for use in agriculture

Abstract

The paper presents the geological characteristics of the limestone of the "Dobrilovići" deposit and the characterization of the trench sample. The technological scheme of limestone preparation, which is used to obtain suitable sizes for use in agriculture, is presented in the paper. Chemical analysis showed the presence of CaCO3 above 80% and CaO above 44.80%. The content of trace metals is low: Cr 21 mg/kg, Pb 3 mg/kg, and Ni 7 mg/kg. The mean value of the loss of ignition is 39.40%, and the pH is 8.47. Based on the obtained results, it was concluded that the chemical and mineral composition of limestone meets the requirements necessary for the calcification of acidic soils. The results of the determination of the granulometric composition showed the dominant presence of large classes above 50 mm (68%). To obtain a class of 100% -2 mm that meets the requirements for application in the calcification of acidic soils, a technological scheme for the preparation of trench limestone is given, which includes crushing, grinding, and grading.
