AB  - In this paper, the combination of FA (Flame Analysis of Noble Metals - Cupellation) and ICP/AES (Atomic Emission Spectrometry with Induction Coupled Plasma) methods for determination of Au and Ag in geological samples of iron ore-magnetite was presented. Au and Ag were concentrated with Pb from PbO after desulphurisation and melting process (Pb2+→Pb). Regulus (Pb with noble metals) is then cupellated. The resulting bead-pril after cupellation was dissolved in HNO3 and then in HCl (imperial water: 2HNO3 and 6HCl). After the preparation of standard solutions and a blank test, the ICP/AES recording is performed. The obtained results were compared with those obtained by the classical method of cupellation. The advantages of ICP/AES are excellent detection limits and linear dynamic range as well as a stable and repeating signal which is particularly important for samples of iron tested due to the low content of noble metals.
AB  - U ovom radu je prikazana kombinacija FA (plamena analiza plemenitih metala-kupelacija) i ICP/AES (atomska emisiona spektrometrija sa indukovanom kuplovanom plazmom) metoda za određivanje Au i Ag u geološkim uzorcima rude gvožđa-magnetit. Au i Agse koncentišu sa Pb iz PbOnakon procesa odsumporavanja i topljenja (Pb2+→Pb).Regulus (Pb sa Au i Ag)se kupelira. Dobijena perla-pril nakon kupelacije se rastvara u HNO3 a zatim u HCl(carska voda 2HNO3: 6HCl). Nakon pripreme standardnih rastvora i blank probe vrši se snimanje na ICP/AES. Dobijeni rezultati su poređeni sa rezultatima dobijenim klasičnom metodom kupelacije. Prednosti ICP/AES su odlične granice detekcije i linearni dinamički opseg kao i stabilan i ponovljiv signal što je posebno bitno za uzorke ispitivane rude gvožđa zbog malog sadržaja plemenitih metala.

AB  - In this paper are showed the results of valorisation of gallium, that is gallium salt gallium(III) chloride, GaCl3, by adsorption with chelate resin and then by extraction with 1, 5 mol/dm3 HCI to GaCl3. The efficiency of used chelate resin adsorption was given which is ca. 10%, while the extraction with HCI is almost completed. In the paper is also presented a mini semi-industrial process of GaCl3 valorisation and there is given the possible block schema of metal gallium receiving from acidic zinc ' liquor.
AB  - U ovom radu prikazani su rezultati valorizacije galijuma, odnosno galijumove soli GaCl3, adsorpcijom Ga2O3 sa helatnim smolama a zatim ekstrakcijom sa 1, 5 mol/dm3 HCl do GaCl3. Data je efikasnost adsorpcije korišćenih helatnih smola koja je oko 10%, dok je ekstrakcija sa HCl skoro potpuna. U radu je prezentirano i mini poluindustrijsko postrojenje valorizacije GaCl3 i data je moguća blok šema dobijanja metalnog galijuma iz kiselog cinkovog luga.

AB  - Depending on the type of black sheet-iron pickling, with the acid sulphate (H2SO4) or sodium sulphate (Na2SO4), before electrolitic drifting of tin, at the production of tinned sheet-irons it was examined morphology of alloyed layer of FeSn2 using SEM microscope and diffraction of X-rays (X-RD). Supposed weight of tin is measured by EDAX analysis. Porosity of the surface was determined by ASTM specification and by potenciostic polarisation. Resistance on corrosion was measured through the ATC test, methods and AC impedance. Achieved results indicates on big importance of pickling type of white sheet-iron at his process of production.
AB  - U zavisnosti od tipa dekapiranja crnog lima, sa sumpornom kiselinom (H2SO4) ili natrijumsulfatom (Na2SO4), pre elektrolitičkog nanošenja kalaja, kod proizvodnje belih limova, ispitivana je morfologija zalegiranog sloja FeSn2 pomoću SEM mikroskopa i difrakcije rendgen zraka (X-RD). Prividna težina kalaja je merena EDAX analizom. Poroznost površine je određivana ASTM specifikacijom i potenciostatskom polarizacijom. Otpornost na koroziju je ocenjena preko ATC testa, potenciostatskih metoda i metode AC impedance. Dobijeni rezultati ukazuju na veliku važnost tipa dekapiranja belog lima u njegovom procesu proizvodnje.
