Abstract

Cilj ovog istraživanja bio je utvrđivanje mineraloškog i kemijskog sastava evaporita iz jalovišta i rudnika Sveta Barbara na Samoborskoj gori. U tu svrhu analizirana su tri uzorka iz rova Sveto Trojstvo, dva uzorka iz rova Kokel i tri uzorka s jalovišta. Uzorci su selektivno otapani kako bi se definirao udio Fe i Cu, odredio udio evaporita naprama EDTA-i netopljivim mineralima u uzorcima iz Ruda i odredio mineraloški sastav EDTA-e netopljivog ostatka evaporita. Udio karbonata i evaporita varira od 77,23 % do 98,86 %. Rezultati odabranih uzoraka Cu variraju od 3,7 do 8,0 ppm, te od 0,01 do 4 vol % Fe. Rezultat EDTA analize ne može sa sigurnošću odrediti točnu količinu evaporita ili karbonata. Mineraloška analiza netopljivog ostatka evaporita ukazuje na kvarc, siderit, pirit i hematit kao dominantne minerale, a u manjim količinama pronađeni su greigit, ilit, klorit, barit i kaolinit.

Abstract: The subject of this thesis is to define mineralogical and chemical composition of evaporites from waste tailings and Sveta Barbara mine. Four samples from Sveto Trojstvo pit, two from Kokel pit and three waste tailings were analysed. Samples were selectively dissoluted to determine Fe and Cu concentration, amount and mineralogical composition of EDTA insoluble residue of the evaporites. Amount of Cu within evaporites varies from 3,7 to 8,0 ppm whereas amount of Fe varies from 0,01 to 4 vol %. Amount of insoluble residue varies from 77,23 % to 98,86 %. Result of EDTA analysis can not determine exact amount of carbonates or evaporites. Mineralogical analysis of unsoluble residue points to quartz, siderite, pyrite and hematite as dominant minerals within evaporites. Greigite, illite, chlorite, barite and kaolinite minerals were found in smaller amount.
