AB  - This review article surveys the subject of choice of high gradient magnetic separation processes for removal of Fe2 O3 carriers from quartz raw material by electromagnetic separator with magnetic field intensity of 1.4 T. The review is based on current experience of authors during research phase, as well as project development phase and initial operation of facilities in several locations. Quartz mineral raw material in those locations appeared as sandstone or as loose material. In addition to that, quartz raw material from those locations contained various impurities, i.e. Fe2 O3 carriers. The choice of this process for Fe2 O3 removal depended on mineralogical composition, shape and the content of minerals, and Fe2O3 removal rate after this process was from 29 to 65%. Magnetic separation is magnetic induction of 1.4 T. It is applied on commercial assortments which were previously subjected to washing and classification processes. It is always the assortment which has to have the lowest Fe2 O3 content. The choice of „dry“ or „wet“ magnetic separation (with water flush) also depends on the fact whether this desired assortment is intended for market as dry or wet, as well as on the composition of magnetic impurities. In most cases, the process applied is the wet one.

AB  - U radu su prikazani osnovni principi na kojima se zasniva magnetska separacija, njena primena, kao i podela minerala prema magnetskim svojstvima. Takođe, date su osnovne karakteristike kvarcnog peska, kao i parametri koji definišu njegov kvalitet za dalju upotrebu. Posebno su prikazani konkretni rezultati primene magnetske separacije u postupku čišćenja kvarcnog peska od magnetičnih nečistoća tipa Fe2O3. Magnetska separacija je urađena na uzorcima kvarcnog peska iz ležišta: „Rgotina“-Zaječar, „Bela Reka“-Bor, „Bijela Stijena“-Skočić i „Avala“-Kopovi Ub. Rezultati su pokazali da je moguće smanjiti sadržaj Fe2O3 u nemagnetičnoj frakciji u odnosu na sadržaj u ulazu. Tako je, na primer, sadržaj Fe2O3 u kvarcnom pesku iz ležišta „Rgotina“-Zaječar smanjen sa 0,086 % koliko iznosi u polaznom uzorku na 0,036 % koliko iznosi posle magnetske separacije.

AB  - U ovom radu su izloženi rezultati laboratorijskih ispitivanja mogućnosti dobijanja PC klinkera sinterovanjem smeše sirovina kojima raspolaže RTB Bor. Obavljeno je sinterovanje smeše krečnjaka iz pogona 'Zagrade', kvarcnog peska iz pogona 'Bela Reka' i jalovine koja nastaje u flotaciji rudnika bakra 'Veliki Krivelj'. Pod istim uslovima sinterovanja (1450°C), obavljeno je i sinterovanje klinkera iz standardne smeše sirovina koje se koriste u FC 'Novi Popovac'. Upoređivanjem rezultata hemijskih analiza i XRD analize dobijenih PC klinkera, utvrđeno je da postoji mogućnost da se PC klinker sinteruje iz sirovina kojima raspolaže RTB Bor. Naime, kada se za sirovinsku smesu koriste krečnjak 'Zagrađe' klase krupnoće - 8+4 mm, kvarcni pesak 'Bela Reka' i flotacijska jalovina u masenom odnosu 81:18:1, dobija se klinker koji je po mineraloškom sastavu adekvatan PC klinkeru dobijenom sinterovanjem sirovina koje se koriste u FC 'N.Popovac'. Ovi rezultati ukazuju na mogućnost primene flotacijske jalovine rudnika bakra u cementnoj industriji, a takođe i na mogućnost dobijanja cementa iz sirovina kojima raspolaže RTB Bor. 1.
AB  - In this work, the possibility to obtain Portland Cement canker by sintering the mixture of raw materials originating from the Mining and Smelting Combine of Bor, on laboratorial scale, was investigated. The sintering mixture was composed of the limestone from the 'Zagrađje' plant, quartz sand from the 'Bela Reka' plant and tailings generated in flotation plant of the 'Veliki Krivelj' copper mine. Under the same sintering condition (1450ºC), a clinker based on the mixture of standard raw materials used in the Cement factory of Novi Popovac was sintered. By comparing the results of the chemical and XRD analysis of obtained Portland Cement clinkers, it was confirmed that it is possible to sinter Portland Cement clinker from the raw materials available from the Mining and Smelting Combine of Bor. By using the combination of the limestone (class - 8+4 mm), quartz sand from the plant and flotational tailings in the ratio of 81:18:1, the clinker whose mineralogical composition corresponds to the PC clinker obtained by sintering the raw materials used in the Cement Factory of 'Novi Popovac', was obtained. Obtained results indicate that the tailings generated by flotation of copper ore can be used in the cement industry; also, that the raw materials available from the Mining and Smelting Combine of Bor can be used to this purpose. .
