This study examined the literature on life cycle assessment ferromanganese alloy production route. The environmental impacts of raw material acquisition through carbon reductants to alloys were and compared. transition from current fossil fuel-based a more sustainable route was reviewed. Besides impact, policy socioeconomic considered due evaluation course differences in routes. Charcoal has po...

OBJECTIVES Little has been known about the risk of cancer associated with occupational exposure to manganese. The objective of this study was therefore to examine the associations between duration of specific work and cancer incidence among employees in four Norwegian ferromanganese and silicomanganese producing plants. METHODS Among men first employed in 1933-91 and with at least 6 months in...

Abstract The Boudouard reactivity of metallurgical coke and densified charcoals was investigated in this study. Potassium is known to accumulate ferromanganese furnaces hence evaluated as a catalyst CO 2 reactivity. Samples were impregnated using gaseous impregnation technique with K 3 .The experiments designed simulate conditions occurring an industrial furnace, used for production Mn-alloys. ...

Geochemical analyses by X-ray spectrometry and laser-induced breakdown spectroscopy (LIBS) instruments on the surface of Mars enable detailed studies materials. The two techniques are utilized in concert rovers to glean information a complementary fashion. However, fundamental differences how these analytical function can produce perceived discrepancies results, such as those resulting from var...
