Nov 03, 2020· Pig iron is a metal material that results when iron ore, charcoal from coal, and limestone are melted together under intense air pressure.When the combined material cools, it forms a high-carbon product known as pig iron.The cooled material is rarely used by itself, as the large amount of carbon makes the material brittle and unstable.

Iron Ore's Role In 2020's Global Economy: Production ...

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

Oct 23, 2020· The US Geological Survey (USGS) collects statistics for both usable iron ore production and actual iron content.In recent years, some sources listed China as the largest producer of iron ore. However, this calculation was based on crude iron ore production. Since much of this crude ore production is low-grade and not usable, reliable sources discount it.

More carbon reacted with the ore and produced a cast iron rather than solid iron. Also, the slag produced was less rich in iron. A different process was used to make "tapped" slag. Here, only charcoal was added to the furnace. It reacted with oxygen, and generated carbon monoxide, which reduced the iron ore to iron metal. The liquefied slag ...

From the Soil to the Iron Product - the Technology … During this process the water content of the iron ore is released, and its structure becomes looser, which makes it easier to smelt. Finally, we break up the burnt iron ore into 2-3 cm pieces to make it easier to load the iron ore into the furnace during the smelting process (See Figure 3). …
