Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace . Pig iron has a high carbon content, typically 3.8–4.7%, [ 1 ] along with silica and other dross , which makes it brittle and not useful directly as a material except for ...

There was an increase in pig iron prices in the early 1870s, which led to the formation of a number of colonial-era iron-making ventures in Australia. A world-wide shortage caused the price of imported pig-iron to increase, from £4 10s per ton in 1870 to £9 per ton in 1873 [1] greatly advantaging locally manufactured iron. This period has ...
Iron ore, coke, and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled, and marketed as pig iron; the rest flows into basic oxygen furnaces, where it is converted into steel.

The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
