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...
Steel production is the most dynamic industry and one of key sectors for development global economy. The growing iron ore increases need its beneficiation granulating subsequent use in steel. As a result, number CO2 emissions harmful substances increases, which negatively affects both society environment. It important to study biomass pellets. Lignocellulosic renewable sustainable source heat e...
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...
Mehdiabad zinc-lead-barite deposit is located in the Central Iran structural zone and about 116 km southeast of Yazd. The host rock of this deposit is Lower Cretaceous dolomitic limestone of the Taft Formation . The main ore minerals in the Mehdiabad East Ridge ore zone include hemimorphite, hydrozincite, cerussite, and chalcophanite. Ore textures are mainly replacement, brecciated, and open-sp...
