摘要:Abstract(#br)Traditional smelting process of manganese ore was plagued with high consume of power and coke, and spraying and slag turning accidents caused by violent decomposition of carbonates and manganese oxides in manganese ore. In the present work, the thermal decomposit...

摘要:Abstract(#br)The present work attempts to investigate the influence of microwave heating on thermal decomposition and dissociation behavior of manganese ore. The manganese ore could be rapidly heated volumetrically to 1000 °C in 17 min by microwave heating, with an increase in manganese...

摘要:Abstract(#br)In-depth understanding of the manganese ore would be beneficial to make the best use more environmental-friendly. A Ghana manganese ore before/after mechanical activation (MA) was therefore extensively characterized in our investigation. Surface Mn 4+ (35.5%), Mn 3...

摘要:...(#br)The oxygen carrier material used in this study consisted of a mixture of ilmenite – which has been used in several studies in CLC – and a manganese ore. Previous studies have shown that gas conversion can be significantly increased by using manganese ore particles...

摘要:Abstract(#br)The use of manganese ore as oxygen carrier has recently gained interest, primarily due to the combination of low cost and moderate to high reactivity. The possibility of an oxygen uncoupling reaction enhancing reactivity may be an additional advantage. In this pap...

摘要:... Low cost materials, such as natural ores, are required for coal-fueled CLC because the lifetime of the oxygen carrier (OC) is lowered by side reactions with the fuel ash or carryover losses. In this study, five manganese ores were examined as oxygen carriers using CO as the ...

摘要:... Production of gaseous O 2 using a manganese ore and the Cu-modified manganese ore as oxygen carriers were investigated. The reaction kinetics of the two oxygen carriers were studied by thermogravimetric analysis (TGA). Multiple O 2 uptake and release cycles were carried out t...

摘要:Abstract(#br)Vertical up-flow constructed wetlands (CWs) with manganese ore (Mn ore) as media (M-CWs) were developed to treat simulated polluted river water. The results showed that the average removal efficiencies for NH 4 -N, NO 3 -N, TN and TP were 91.74%, 83.29%, 87.47% and 6...

摘要:Abstract(#br)Manganese ores differ extensively in their mineralogical and bulk chemical composition. Consequently these ores follow different mineralogical morphology development paths as the reduction reaction proceeds in the production furnace. Mineralogical factors such as co...

摘要:Abstract(#br)The genetic evolution of three types of reworked manganese ore bodies namely: Detrital, Concretionary (Mangcrete) and Wad in the Precambrian Iron Ore Group occurring in Bonai-Keonjahr belt, Singhbhum Craton, India are reported. All the reworked Mn-ore bodies are dev...
