2021-5-5  Iron ore. In the vicinity of coal, it is regenerated by heat in the furnace and then melted by a stream of hot regenerative gases produced by burning the coke in the hot air below the furnace and moving in the opposite direction of the iron path. The molten iron and pulp from the ore are discharged from the furnace furnace every two to four hours.

Extracting iron from iron ore using a Blast Furnace

2011-8-3  Extracting iron from iron ore using a Blast Furnace Introduction Fe 2 O 3, and magnetite, Fe 3 O 4. Note: The two equations for the reduction of the ore on this page are for haematite. In the fairly unlikely event that you need the equations for magnetite, they aren't difficult to work out for yourself.

Understanding the high-grade iron ore market

2021-3-26  Blast furnace vs direct-reduction ironmaking horses for courses There are two main technologies for converting iron ore (iron oxide) into metallic iron: the blast furnace (BF), which is by far the most common, and the direct-reduction (DR) route, which accounts for just over 100 million tonnes per year (tpy), or around 8% of global primary iron
