iron ore application process

 · Traditional iron ore reduction utilizes a chemical reaction between iron oxide and carbon monoxide sourced from heating coke fuel in a blast furnace. Coke is a hard, porous, nearly pure carbon product made by heating coal in the absence of air (in coke ovens). Coke acts as both a fuel and reducing agent in the blast furnace, forming carbon monoxide when burned, and reacts with the iron .

Fines ranging from 6 to 40% arise when iron ore is directly reduced. These fines are difficult to handle and to process in a melting vessel. Thus size enlargement is required. In the briquetting process, fines are usually bound using water glass with hydrated lime. There are alternatives of equivalent quality, such as sulfite lye or molasses. For the cold briquetting of sponge iron, specific ...

The selection of iron ore for a blast furnace is traditionally influenced by a number of factors that determine the economics and practicalities of a successful operation.
