Abstract | Full Text

In this paper are presented the results of testing the possibilities of improving the technological process evaluation lithothamnium limestone deposits 'Dobrilovići' - Loznica in order to obtain a new range of products including: flue gas desulphurization (ODG), as feed additive and for liming acid soils. The results showed that the limestone from this deposit may be used for ODG as it meets the requirements of the required quality for use in these purposes. In fact, the raw materials meet the requirements for obtaining a powder (bulk) gypsum. Comparing the characteristics of the resulting range to be used as a feed additive ('fodder chalk') and the requirements to be met by this product, we can say: selective excavation and selecting a particular size class can get this range of products. The results of laboratory tests of briquettes obtained from lithothamnium limestone have shown that it is possible to obtain briquettes of a satisfactory quality. Values of parameters of the mechanical properties of briquettes increases with the share of bentonite as a binder in the samples. This increase in samples with mass proportion of binder to 5% is a linear growth, while for the samples containing more than 5% of binder that trend is minimal. Therefore, there is no need to produce briquettes with more than 5% of bentonite. Based on the results of laboratory tests, authors have proposed technological scheme by which is possible complete evaluation of the limestone deposit 'Dobrilovići'. With adaptation of existing technology line in the firm Department for Agriculture 'Loznica' Ltd. (which owns the mine limestone 'Dobrilovići') can be obtained three new product range.
