In the early days of iron ore's derivatives market development, the Singapore Mercantile Exchange (SMX) was one of the first exchanges to offer a futures contract, based on Metal Bulletin's 62% Fe index in 2011. The Singapore Exchange (SGX) also launched a low-grade iron ore contract settled against Met…

The iron ore fines and concentrate cannot be directly utilized in blast furnace, and therefore, its agglomeration i.e. enlargement of particle size is necessary before it is used as feed for iron making. Sintering is one of the methods of agglomeration. All iron oxide bearing wastes and coke breeze is used for sintering purpose.

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.
