Besides iron ore agglomeration, these pelletizers can also be used for other materials such as copper ore, gold ore, coal, and fertilizer [12]. ... In recent years, sinter feed has proven to be a good place to blend in various process dusts and sludges that contain iron values, but cannot be directly fed into the furnace. In addition, fluxes ...

As there can be significant variation in process requirements and sources of iron ore fines, testing is often an essential part of the development of a successful iron ore pelletizing operation. Different sources of iron ore will respond differently to agglomeration, and process requirements will subsequently vary.

Iron ore sintering is a pretreatment step of smelting that agglomerates the iron ore using surface melting of green pellets to improve the quality of the steel product. The sintering process not only improves the quality of steel products, but also releases CO and CO2 gases, evaporates moisture, and improves the reducibility of iron ore to ensure smooth operation of the blast furnace. These ...

A novel iron ore agglomeration process using concentrated solar flux, called a solarbased LMP process is proposed. The process has been tested using laboratory experiments inside a hybrid solar simulator reactor setup. The results indicate no change in the reaction mechanism of LMP formation under solar irradiation compared to electrical heating.

Iron ore powder agglomeration processes include sintering, pelletizing, and briquetting. The product from sintering process is called sinter, the product from pelletizing process is called pellet (Fig. 1 ), and the product from briquetting process is called "briquette."

Satyendra. Sintering and palletization are two different processes of agglomeration. Major advantages of sintering process are (i) Sintering uses as mined iron ore fines which can be used as such without further activity of grinding (ii) Sintering can use a very amount of waste materials (iii) Sinter can be made with high basicity thus eliminating direct charging of limestone and dolomite in ...

ABSTRACT In steel industry and in mines, a significant amount of ultrafines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultrafines materials. Pelletizing can use ...
