agglomeration of ore by sintering
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.

Sintering Characteristics of Indian Chrome Ore Fines
With the increase in the coke breeze addition from 2.8 to 5.5 pct (normally used for iron ore sintering), an agglomeration of ore could be achieved with a lower sintering time. Although both the sinter strength and granulometry showed improvement, the ETI remained unsatisfactory. This indicates that, with the absence of flux, a 5.5 pct …
