Effects of Fuel on Gasification Dephosphorization of High-Phosphorus Oolitic Hematite Ore

Abstract

Through using jiuquan bituminous coal, yangquan anthracite, coking coal and charcoal as fuel,under 900 °C simulating the preheat layer of sinter process,research the influence of fuel types and content on gasification dephosphorization.Results show that due to the different volatile matter of coal, the influence on gasification dephosphorization is different, the influence of the highest volatile bituminous coal to the dephosphorization effect is best when carbon content takes 4%.

Studying on mineralogical characteristics of a refractory high-phosphorous oolitic iron ore

“…Apatite crystals, mainly in pillar, acicular, or aggregated shapes or in the form of dispersed particles, are embedded in iron minerals and gangue minerals, and are characterised by their fine granularity. Some are refractory iron ores with granularity of less than 2 μm, resulting in difficulty in their separation [15][16][17][18].…”
