Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and
Outotec® Pallet Cars for sintering and pelletizing Outotec offers unrivalled solutions and services for processing minerals and metals. Our processes for sintering and pelletizing have been the world''s leading solutions for iron ore sinter and pellet production for over 50 years. The main feature is a traveling grate

Method 2 Agglomeration Dedusting the fine coal dust is another method of disposal. Fine coal dust does not readily mix with water, so a high-speed pin mixer is used to accomplish the dedusting (Figure 2).No additional chemicals are employed.. This mechanical processing produces a mixture which resembles a rich black soil and will ball when compressed in one''s hand, but will fall apart when ...
Pelletizing of raw material by combining agglomeration with thermal energy is increasingly being used as a method of value adding. Pelletizing is typically used in the iron ore industry to convert raw ore into pellets with characteristics appropriate for use in a blast furnace. It is also popular in the chemical and food industries and .
Pelletizing is a process for the agglomeration of very fine-grained ores. Outotec''s process involves two stages: the forming of moist globules (green pellets) and then a hardening phase. Pellet hardening occurs through crystallization processes, grain growth and structural changes. Hardening requires burning the
Processing Module Quiz Set. Sinter and coke are alternately charged and hot blasted at 1200 degrees celsius. Coke contributes carbon, which reduces Iron oxide to iron and carbon monoxide gas. Lime is a flux (calcium oxide), and this is a good flux because it is not reduced by carbon, and collects all the impurities from the walls of the furnace.
First, an agglomerative hierarchical clustering procedure using the centroid method and Squared Euclidean distance was used to determine if common decision-making strategies existed among couples when making joint likelihood ratings for movies to view together.

The principle of sintering involves the heating of iron ore fines along with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace. It is basically an agglomeration process achieved through combustion.
An application of limonite as grate-layer material in producing spherical agglomerate features that its layer thickness is 30-40 mm and its granularity is 10-25 mm. The raw materials for producing spherical agglomerate include returned ore (10-20 wt.%), calcium lime (2-10), lime stone (0-12), dolomite (0-12), solid fuel (3-7.5) and Fe-contained material (rest).
Hybrid Flotation Technology of Primetals Technologies combines a pneumatic spray principle with a column method. The technology is based on the merging of feed pulp (slurry) and gas (air or nitrogen) in the mixing chambers of the ejector system before spraying it into the cell – with short retention times.

Additionally, it is the objective to eliminate the gaseous emissions by eliminating some steps in pre-processing and to eliminate sintering, pelletizing and coke making. These goals will be accomplished by using an alternate method of agglomeration, iron oxide mixed with a carbon for direct feed to a smelter and feeding any type smelter that hot metal can be produced.
Pelletizing and Sintering Pelletizing of raw material by combining agglomeration with thermal energy is increasingly being used as a method of value adding. Pelletizing is typically used in the iron ore industry to convert raw ore into pellets with characteristics appropriate for use in a blast furnace.
Diverse recycling methods/route for the utilization of ﬁne and moist materials are available. Sintering, pelletizing and briquetting (Fig. 2) are the three conventional technologies widely being used for agglomeration of ore ﬁnes. High capital investment coupled with the introduction of gangue through solid fuel prohibits the use of sintering process.
