Iron ore sintering
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics. Iron ore sinter typically constitutes more than 70% of the blast ...

Sintering: A Step Between Mining Iron Ore and Steelmaking
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Evaluation of concentrated solar thermal energy for iron ore
A novel iron ore agglomeration process using concentrated solar flux, called a solar-based 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.
