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.
Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...

Blast Furnace Anatomy #1 – To the Heart of Steelworks Operation
First, the iron ore, the raw materials for steel, comes from the Earth. Most iron ores — hematite, magnetite, limonite — contain an average of 60% of iron (Fe). Before the iron ores enter a blast furnace, it undergoes 'sintering' which turns the pristine iron ore into more compact and appropriate sizes.
Blast Furnace Ironmaking
Blast furnace uses iron ore as the iron-bearing raw materials, and coke and pulverized coal as reducing agents and heat source, lime, or limestone as the fluxing agents. The main objective of blast furnace ironmaking is to produce hot metal with consistent quality for BOF steelmaking process.
