Manganese ores are promising oxygen carriers for chemical looping combustion (CLC), due to their high reactivity with combustible gases. In this work, a manganese ore called EB (Elwaleed B, originating from Egypt) is studied its reaction rate CH4, CO and H2 the data used in an analytically solved reactor model. The of fresh three samples previous operation 10 kWth pilot was examined batch fluid...

Pseudonannolene spelaea n. sp. is the first strictly cave-dwelling species described for the family Pseudonannolenidae. It is found in iron ore caves in the Brazilian Amazon. The family Pseudonannolenidae is exclusively Neotropical and frequently found in caves of Brazil, from which 20 species are known. The new species is compared with its congeners and with related cave-dwelling species. The ...

Magnetic separation is often considered pertinent for manganese ore beneficiation when the abundant with siliceous rich gangue mineral phases. However, process deemed to be inapposite ferruginous type of ore, and remains a grey area research. In present investigation, two different types were studied in detail understand influence mineralogy on their magnetic performance. Detailed experiments p...
