Abstract:
Difficult access to the field in Central Sulawesi causes the process of identifying prospects for mining minerals requires a relatively large time and cost. Therefore, the remote sensing approach can be carried out as a preliminary study to determine the distribution of hydrothermal alterations that characterize the presence of mine minerals. This study utilizes Landsat 8 imagery to obtain the distribution of alteration minerals, especially the group of ferrous mineral oxide and hydroxide minerals, clay and carbonate minerals and Ferromagnesian minerals. The method used is composite (RGB) 4/2,

Abstract:
Abstract Ciprofloxacin bioavailability may be reduced when ciprofloxacin is co-administered with metallic ion containing preparations. In our previous study, physicochemical interaction between ciprofloxacin and ferrous sulphate was successfully simulated in vitro. In the present work, comparative in vitro ciprofloxacin solubility and dissolution studies were performed in the reactive media containing aluminium hydroxide, calcium carbonate or zinc sulphate. Solid phases collected from the dissolution vessel with aluminium hydroxide, calcium carbonate and zinc sulphate were investigated for the

Abstract:
The purpose of this study is to determine the phase composition of iron oxide compounds formed during precipitation by ammonium carbonate hydrolysis products, to establish the magnetite formation regions and the kinetic characteristics of the reaction formation Fe3O4. Characterization by X-ray diffraction (XRD) indicated that magnetite is formed in a solution of ferrous sulphate during the hydrolysis of ammonium carbonate. It has a homogeneous phase composition and a cubic crystal structure. Phase diagrams of the formation of the crystalline phase of magnetite, goethite and ferric hydroxide ha

AbstractThe preparation of green rusts from sulphate solutions and representative Mössbauer spectra are described. As the samples oxidized readily, attention focused on the Mössbauer parameters at liquid nitrogen and helium temperatures. The spectra recorded at 77 K could be fitted satisfactorily with one ferrous iron quadrupole doublet with a separation of 2·93 mms−1 and one ferric iron quadrupole doublet with a separation of 0·45 mms−1. In some spectra a ferric iron magnetic hyperfine of strength 49·2 T was also apparent. At 4·2 K, the ferrous iron exhibited a hyperfine splitting with a fiel

Abstract:
The subject of this study was the steel pipes that are part of Belgrade's drinking water supply network. In order to investigate the mutual effects of corrosion and water quality, the corrosion scales on the pipes were analyzed. The idea was to improve control of corrosion processes and prevent impact of corrosion on water quality degradation. The instrumental methods for corrosion scales characterization used were: scanning electron microscopy (SEM), for the investigation of corrosion scales of the analyzed samples surfaces, X-ray diffraction (XRD), for the analysis of the presence of solid f

Abstract:
Abstract The zinc content of basic oxygen furnace (BOF) sludges is too high for direct recycling into the blast furnace via the sinter plant, as excessive zinc concentrations are detrimental for the refractory lining of the blast furnace. However, by partial and selective removal of zinc from the BOF sludge, the residual sludge can be used as a secondary iron resource in the blast furnace. In this paper, BOF sludge was leached with aqueous ammonia, aqueous solutions of ammonium salts (chloride, carbonate, and sulfate), and aqueous mixtures of ammonia and ammonium salt.

Abstract:
Unit operations (UO) are mostly used in non-ferrous extractive metallurgy (NFEM) and usually separated into three categories: (1) hydrometallurgy (leaching under atmospheric and high pressure conditions, mixing of solution with gas and mechanical parts, neutralization of solution, precipitation and cementation of metals from solution aiming purification, and compound productions during crystallization), (2) pyrometallurgy (roasting, smelting, refining), and (3) electrometallurgy (aqueous electrolysis and molten salt electrolysis).

Abstract:
L’arsenic est un métalloïde toxique pour l’homme. L’adsorption de As sur les oxydes de fer, qui contrôle sa mobilité dans les aquifères, est fortement influencée par l’activité microbiologique qui influe sur le redox de ces deux éléments. Les réductions bactériennes peuvent mobiliser l’arsenic adsorbé sur les oxydes de Fe(III). Néanmoins, il a été montré que les minéraux néo-formés portant du Fe(II) pourraient re-piéger une fraction de As libéré par ces bioréductions. Au moment où cette étude a été initiée, le devenir de l’arsenic adsorbé lors de la réduction des oxyhydroxydes ferriques était
