HIsmelt Process of Ironmaking
HIsmelt is short for 'high intensity smelting'. It is a direct smelting process for making liquid iron straight from the iron ore. The process has been developed to treat iron ore fines with minimum of pre-treatment, making the process more flexible in terms of the quality of iron ore it can treat. The process allows the use of non coking ...

Iron
Obtaining. Due to its high smelting temperature, iron ores cannot be simply melted down in a crucible like bronze or copper.Instead, iron ore nuggets (in the form of hematite, limonite or magnetite nuggets) must be smelted in a bloomery to produce iron blooms, which are further refined on a bronze or better anvil into wrought iron, which can then be smithed into tools.

Pig Iron Manufacturing Process
In the latest report of the engineers at Trollhattan, it is stated that the power consumption per ton of pig iron varies in proportion to the iron content of the ore. A poor ore and pig iron high in silicon and manganese require more power than a rich ore and pig iron low in silicon and manganese. This was also found to be the case in California.
