consumption of coke in iron ore pelletising process

for iron makers Pelletizing process The pelletizing process was selected for this study due to its popularity in ironmaking business and the ability to produce uniform-sized pellets at high capacity and low cost Pellets are made from iron ore concentrates that have an average iron (Fe) content of at least 60% and particle size of 80%75 μm Sinter is a combination of iron ore fines fluxes and coke agglomerated through heat Using our extensive expertise in iron and steel operations we can advise on developing sintering operations that produce sinter with the optimum physical and metallurgical properties

Steel is mainly produced via two different process routes the path from "iron ore to steel" and the path from "scrap to steel" With the iron-ore based route hot metal is mostly produced from iron oxide ores in blast furnaces and more rarely in smelting reduction plants and is processed to make crude steel in oxygen converters

Iron Ore and Pellets

Iron ore is found in nature in the form of rocks mixed with other elements By means of various industrial processes incorporating cutting-edge technology iron ore is processed and then sold to steel companies The iron ore produced by Vale can be found in houses cars and appliances

Many iron ore producers are facing challenging times processing crude material with rising levels of impurities and a volatile iron ore price Beneficiation particularly washing (scrubbing) can be the key to upgrading the ore to earn more per shipped tonne High-end steel production at a low coke consumption level and a high productivity rate can only be achieved by using high-quality

A study was carried out to compare the environmental impacts of the two major iron ore agglomeration processes sintering and pelletising using life cycle assessment (LCA) methodology The following agglomeration processing routes with the fuel options shown were investigated sintering with combined natural gas/coke breeze or charcoal as fuel

Sintering or pelletising improves the blast furnace operation and reduces energy consumption Direct reduction produces sponge iron from iron ore pellets by using natural gas Most iron is produced from sintered iron ore and coke The steel maker controls the sintering process to produce a consistent iron

Iron ore pellets and Pelletizing processes | ispatguru Feb 23 2013 Iron ore pellets and Pelletizing processes Pelletizing is a process Growth occurs in the subsequent revolutions of the disc by the addition of more fresh feeds and by collision between small pellets
