Litijum u mineralnim vodama Srbije – potencijalna lekovita svojstva
Jana Štrbački (2022)Litijum je biološki aktivan mikroelement u ljudskom organizmu: u malim koncentracijama doprinosi pravilnom funkcionisanju pojedinih enzima, hormona i vitamina, dok se u većim, terapeutskim dozama, koristi za lečenje i prevenciju nekoliko psihijatrijskih poremećaja. Eksperimentalno je dokazano da su litijumske mineralne vode bioraspoloživi izvor ovog mikroelementa, u smislu obezbeđivanja njegovog preporučenog dnevnog unosa. Proučavanjem zakonomernosti raspodele litijuma u mineralnim vodama Srbije konstatovano je da barem 50 pojava sadrži koncentracije litijuma potrebne za unapređenje opšteg zdravstvenog stanja ljudi.Jana Štrbački.

Model za optimizaciju graničnog saržaja metala u rudi u funkciji dugoročnog planiranja površinskih kopova
Daniel P. Kržanović (2016-06-14)Optimizacija graničnog sadržaja metala u rudi jedan je od osnovnih koraka u planiranju i dizajniranju površinskih kopova i ima za cilj postizanje maksimalne neto sadašnje vrednosti (NPV). Iz tog razloga, optimizacija graničnog sadržaja i danas je predmet mnogih istraživanja u rudarskoj nauci, sa ciljem rešavanja praktičnih problema u eksploataciji ležišta.Dugoročno planiranje eksploatacije na površinskim kopovima podrazumeva sagledavanje svih relevantih parametara i faktora (geologije rudnog ležišta, tehnologije proizvodnog procesa, kapaciteta otkopavanja i prerade, troškova, cena metala, iskorišćenja i dr) kako ...površinski kop, dugoročno planiranje, optimizacija graničnog sadržaja, maksimizacija neto sadašnje vrednosti (NPV).... flotacijsko iskorišćenje minerala 1 (%) y1 metalurško iskorišćenje minerala 1 (%) cf2 flotacijsko iskorišćenje minerala 2 (%) y2 metalurško iskorišćenje minerala 2 (%) p1 cena minerala 1 ($/t) p2 cena minerala 2 ($/t) r1 troškovi metalurške prerade minerala 1 r2 troškovi ...

Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.

Mafic alkaline metasomatism in the lithosphere underneath East Serbia: Evidence from the study of xenoliths and the host alkali basalts
Effects of mafic alkaline metasomatism have been investigated by a combined study of the East Serbian mantle xenoliths and their host alkaline rocks. Fertile xenoliths and tiny mineral assemblages found in depleted xenoliths have been investigated. Fertile lithologies are represented by clinopyroxene (cpx)-rich lherzolite and spinel (sp)-rich olivine websterite containing Ti–Al-rich Cr-augite, Fe-rich olivine, Fe–Al-rich orthopyroxene and Al-rich spinel. Depleted xenoliths, which are the predominant lithology in the suite of East Serbian xenoliths, are harzburgite, cpx-poor lherzolite and rare ...Cvetković Vladica, Downes Hilary, Höck Volker, Prelević Dejan, Lazarov Marina.
