I N T R O D U C T I O N Some coal-based i ron ore direct reduc t ion processes are based on format ion of composi te pellets which consist of a mix ture of fines of i ron-bear ing oxide, carbonaceous mater ia l , for example, coal, coke, or char and a smal l a m o u n t of binder . ...
Gazestan deposit is located about 185 km of Yazd, in the Bafgh – Posht e Badam Metallogenic belt, consists of Infracambrian carbonate, shale, tuff, sandstone and volcanic rocks. Acid to basic green rocks (rhyolite, dacite and basalt) are host for iron and phosphate mineralization. The alteration process is more intence in the volcanic rocks including, actinolite, chloritization, silicification ...
Naphthalene is an ubiquitous pollutant of the environment and the biodegradation of this pollutant has been receiving constant scientific consideration. The aim of this study was to isolate and identify bacteria that could degrade naphthalene from three regions of the Gol Gohar Mine at Sirjan, Iran. In this study, the total naphthalene degrading bacteria were quantified with the most probable n...
determination of relationship between autoignition of sponge iron and specification of the iron ores
sponge iron (dri) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). in this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. isothermal and non-isothermal re-oxidation experiments were carried out on each type of dri and their autoignition...
Development and implementation of large-scale industrial projects in complex eco-epidemiological settings typically require combined environmental, social and health impact assessments. We present a generic, spatio-temporal health impact assessment (HIA) visualization, which can be readily adapted to specific projects and key stakeholders, including poorly literate communities that might be aff...
Herein a big Fe-C-Ca cycle, clarifying the basic element flows and energy flows in modern carbon-intensive industries including the metallurgical industry and the cement industry, was proposed for the first time in the contexts of emission reduction and iron ore degradation nowadays. This big cycle was focused on three industrial elements of Fe, C and Ca and thus it mainly comprised three inter...
Iron-rich (ferruginous) ocean chemistry prevailed throughout most of Earth's early history. Before the evolution and proliferation of oxygenic photosynthesis, biological production in the ferruginous oceans was likely driven by photoferrotrophic bacteria that oxidize ferrous iron {Fe(II)} to harness energy from sunlight, and fix inorganic carbon into biomass. Photoferrotrophs may thus have fuel...
