Fungal Leaching of Manganese Ore
Bioleaching is technologically feasible for extraction of manganese from low grade ores (containing manganese less than 35% by weight). The principle involves the non-enzymatic reduction of pyrolusite [Mn(IV) oxides] to +2 oxidation state by fungi with the production of metabolites such as oxalic acid and citric acid. In the present investigation, a fungal strain, Penicillium citrinum was isola...
متن کاملReactions in Mixed Non-aqueous Solutions containing Sulphur Dioxide. Part 7.' A Raman Spectroscopic Study of Adduct Formation between Sulphur Dioxide and Dimethyl Sulphoxide
Details are given of the v ( S O ) ~ ~ ~ ~ stretching (dmso = dimethyl sulphoxide), v,(SO,), v,(SO,), and v,(SO,) regions of the Raman spectra of SO,-dmso mixtures at 293 K and sub-ambient temperatures. Analysis of the v( SO)dmso region, which contains at least seven component bands, provides evidence of several component species. Bands at 1 067,l 057, and 1 044 cm-l are due to monomers and ass...
متن کاملAdsorption and Coprecipitation of As(V) from Aqueous Solutions by Manganese Dioxide
The effects of solution pH and initial concentration on adsorption and coprecipitation of As(V) from aqueous solutions by manganese dioxide [MnO2] for 50d and 1120d were studied. The XRD, FT-IR and SEM results indicated that there was only slight difference between the MnO2 adsorbents before and after adsorption, but their crystal structure had not changed. For the initial As(V) concentration C...
متن کاملDISSOLUTION KINETICS OF MANGANESE DIOXIDE ORE IN SULFURIC ACID IN THE PRESENCE OF FERROUS ION
Abstract: In this paper, kinetics of reductive leaching of manganese dioxide ore by ferrous ion in sulfuric acid media has been examined. Experimental results show that increasing temperature from 20 to 60 °C and decreasing ore particle size from −16+20 to −60+100 mesh considerably enhance both the dissolution rate and efficiency. Molar ratios of Fe2+/MnO2 and H2SO4/MnO2 in excess to the st...
متن کاملInvestigation of Leaching Kinetics of Smithsonite Ore
The leaching kinetics of smithsonite ore in acetic acid solutions, an environmental friend, and natural reagent was investigated. The influence of parameters such as reaction temperature, particle size, solid-liquid ratio and acid concentration was studied in order to reveal the leaching kinetics of smithsonite ore. In this study, experimental and statistical methods were carried out in order t...
