Abstract

The reduction of nitrogen compounds and thiosalts in mining industry is extremely important for sustainable management of ecosystem and human health. The goal of the present thesis was to assemble and test a pilot water treatment plant for simultaneous removal of nitrogen and thiosalts compounds at Boliden Mineral AB in Boliden, Sweden. This pilot project is important part of Boliden Mineral AB environmental policy to constantly improve environmental performances of mineral processing. The work is undertaken at Boliden in period February 25 – August 15, 2019. In first three months of work the pilot plant was assembled, followed by the plant testing from June 14 to July 27 (in total 24 work days of testing). With this work removal is achieved partly. Nitrogen compounds are removing more than thiosalts. Thesis will state problems and solutions for better removal of these compounds.

Abstract (croatian)

Smanjenje koncentracija dušikovih komponenti I tiosoli u rudarstvu je izuzetno važno za održiv razvoj ekosustava I ljudskog zdravlja. Cilj ovog rada je sastaviti I testirati probno postrojenje za simultano uklanjanje dušikovih spojeva I tiosoli. Sva ispitivanja su napravljenja za kompaniju Boliden Mineral AB, u gradu Boliden, Švedska. Ovo ispitivanje je izuzetno važno za Boliden, s obzirom da je krajnji cilj kontinuirano usavršavanje I poboljšavanje kvalitete I očuvanje okoliša. Rad je izvršen u periodu of 25. veljače do 15. kolovoza 2019. godine. U prva tri mjeseca probno postrojenje se prilagođavalo potrebama. U periodu od 14. Lipnja do 27. Srpnja izvršena su sva mjerenja I zabilježena opažanja. U ovom radu uklanjanje je bilo djelomično uspješno. Dušikovi spojevi su uklonjenji u većim koncentracijama nego tiosoli. Ovim radom biti će istaknuti I opisani problemi I rješenja za što uspješnije buduće uklanjanje ovih komponenti
