Sažetak
Mining activity in the Republic of Croatia is based mainly on the exploitation and production of non-metallic mineral raw materials. Since carbonate rocks are predominant in the geological structure of Croatia, in the majority of quarries limestone and dolomite are exploited. Dolomite is widely used in various industries e.g. construction industry, building material industry, metallurgy, glass industry, etc. In glassmaking it is added to raw material mixture in the form of dolomite grits (- 1 mm) as one of the essential components for the input of glass modifiers that is CaO and MgO. To be used for this purpose, dolomite has to meet certain standard specifications established by the glass industry. In most cases, dolomite exploited in quarries does not satisfy demanding specifications and, therefore, its further processing is needed. The paper describes processing technology for dolomite intended for use as a raw material in container glass production. Fe2O3 content in exploited dolomite before beneficiation varies in range from 0.052% to 0.07%. By beneficiation procedure applying dry magnetic separation, dolomite grits with Fe2O3 content less than 0.05%, which meets the requirements of container glass industry, are obtained. The results presented in this paper are achieved under field conditions.
