Nsintering process of iron ore pdf files

In this model it is assumed that the liquid phase formed will move together with the remaining solid phase due to the viscosity, thus, equations for momentum transfer and. Pdf fine particle processing of iron ore slimes from. Process brief sintering process is developed mainly to utilize under size of lump ore called iron ore fines. Mineralogy of iron ores of different alumina levels from. The technology aims to improve the recovery of iron ore still contained in wastes or low grade rom making it possible to obtain iron ore concentrate with. Some rare metal elements such as mn, nb and v are contained along with p in iron ore.

The purpose of the sintering process is manufacturing a product with the suitable characteristics thermal, mechanical, physical and chemical to be fed to the blast furnace. Major problem faced with the indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel. One of the possibilities to increase iron content in sinter is the modification of raw materials ratio. The iron ore sintering is carried out by putting mixture of iron bearing fines mixed with coke breeze on as permeable grate. Please use purchased version to remove this message.

The paper enumerates the developments in ecofriendly processing of iron ore slimes by state of art vertical pulsating wet high. Influence of iron ore mineralogy on sinter strength the iron bearing minerals have different characteristics. The metallurgical properties of an ore depend on its specific mineralogy and textural characteristics, including the nature of the pore spaces. The process of sintering is basically a pretreatment process step during iron making for the production of the charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes collected dusts, sludge and mill scale etc. As a resource strategy in japan, the possibility of efficient recovery of these elements as byproducts of. Fine particle processing of iron ore slimes from wash plant. The top layer of this sinter bed is this pdf file is created by trial version of quick pdf converter suite.

The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent. In order to conserve these, otherwise waste material, they are compacted together and made into lumps by a process known as sintering. Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents and solid fuel coke. Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents, and solid fuel coke. Iron ore sintering process optimization optymalizacja procesu aglomeracji rudy zelaza the work deals with examination of the influence of the ratio between iron ore concentrate and iron ore on quality of produced iron ore sinter. Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be. Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as gangue.
