چکیده
The synergetic utilization of ferruginous gibbsite ores (Al-Fe ores) and manganese (Mn-Fe by the carbothermic co-reduction roasting–magnetic separation process was proposed as an innovative green for recovery valuable metal elements Mn, Fe Al from these ores. In this paper, a ferromanganese crude alloy with 72.47% 10.19% Mn high 85.89% prepared, which produces acceptable feed to produce steels electric arc furnace. synergistic two kinds complex refractory minerals favored separate Fe, influence operating variables on metals Mn-Fe Al-Fe is initially studied. Then, stepwise reduction behaviors composite oxide Mn1-xFexO (0 ≤ x 1) hercynite (Mn1−yFeyAl2O4, 0 y were investigated clarify that have positive impact fayalite in This study reported simple route, co-reduction–magnetic process, economically effectively treat

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 کاملMicrowaves Applied to Carbothermic Reduction of Iron Ore Pellets
Results of reducibility tests of reduction conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as reducing agent with conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume. Ore used in this work is called "Alzada" which has reducibility ...
متن کاملBiogeochemistry of manganese in ferruginous Lake Matano, Indonesia
This study explores Mn biogeochemistry in a stratified, ferruginous lake, a modern analogue to ferruginous oceans. Intense Mn cycling occurs in the chemocline where Mn is recycled at least 15 times before sedimentation. The product of biologically catalyzed Mn oxidation in Lake Matano is birnessite. Although there is evidence for abiotic Mn reduction with Fe(II), Mn reduction likely occurs thro...
متن کاملThe Smelting of Manganese Carbonate Ore
The practice of manganese ferroalloy smelting has traditionally been based on utilising oxide ores which typically contain a high level of manganese. This preference for oxides has even been extended to the modification of natural carbonates into nodulized oxides. However smelting practices developed over the past 30 years have created a market for natural manganese carbonate ores, driven in pa...
