Gleptoferron, a sterile aqueous colloidal solution of beta-ferric oxyhydroxide and dextran glucoheptonic acid, was compared with iron dextran for the prevention of Fe deficiency anemia in young pigs. Using 26 litters, pigs (within each litter) were randomly allotted to one of three treatments: 1) control (no Fe), 2) iron dextran (200 mg) and 3) gleptoferron (200 mg). Blood was collected at 0, 1...

Zinc contaminated steelmaking by-products such as blast furnace (BF) dust and basic oxygen (BOS) present a significant recycling challenge at integrated plants. Rotary Hearth Furnaces (RHFs) provide an attractive route for recovery of Fe Zn from these materials through carbothermal reduction the oxides in material to yield Direct Reduced Iron (DRI) crude zinc oxide. The next generation RHF proc...

Abstract Metallurgical grade alumina is produced worldwide through the well-known Bayer process, which unavoidably generates bauxite residue (BR, also known as red mud) in almost equal amounts to alumina. This study aims valorization of BR a smelting-reduction process obtain calcium aluminate slags that can be proper feed for recovery via Pedersen process. It investigates thermodynamics and cha...

This study is aimed at developing a technology for processing electric arc furnace dust (EAFD) into granulated cast iron and zinc-containing product. The object was the from EAF of PJSC Magnitogorsk Iron Steel Works (Magnitogorsk, Chelyabinsk region). It has been established that contains valuable components in form ZnFe2O4 ZnO. EAFD involves reduction Fe Zn charge their oxygen-containing forms...

      Flavonoids could serve as potent inhibitors of xanthine oxidase (XO). In the present study, the effects of Ruta graveolens L. extract and its major isolated flavonoids, quercetin and rutin, on guinea pig liver XO have been investigated. The inhibitory effects of R. graveolens, quercetin and its glycoside form, rutin, were assayed spectrophotometrically. R. graveolens...

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

The excessive production of bauxite residue (red mud) in the Bayer process is one major challenges amongst alumina producers. Pedersen known as a combination smelting reduction and leaching treatment produced slag for production, also produces an inert (grey mud), which more suitable further processing compared to red mud. This paper describes life cycle assessment two processes, current commer...
