The term cast iron refers to iron-carbon-silicon alloys that contain 2.5-4 % carbon and usually 1-3 % silicon. In grey irons, the carbon is present as graphite; in white cast iron it is present in the form of iron carbide and alloy carbides. Cast iron has good castability and machinability, as well as moderate mechanical properties.
A historical overview of the origin and evolution of ferrous metallurgy, fundamentals of producing iron and its alloys, is presented. The paper shows the sequence of discoveries behind the technology of iron and steel, the effect of carbon on the formation of cast iron and steel, as well as the progress in foundry and thermomechanical …

The Mega Hub aims to produce low-carbon products such as hot briquetted iron (HBI) for the steelmaking industry, with a focus on using clean energy and green hydrogen. The signing of these agreements marks an …
Multidisciplinary research on the metallurgy-related items and features from the ancient South Arabian harbour of Sumhuram, in southern Oman, have shed light on ancient copper and iron production and use at the site, pointing out what appears to be a definitely unusual practice in particular for what concerns copper alloying.
Microstructures of Cast Iron Janina M. Radzikowska, The Foundry Research Institute, Krako´w, Poland CAST IRON is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentia-tion from steel and cast steel, cast iron is defined as a cast alloy with a carbon content (min2.03%)

Early procedures of metal-ore melting relied on the use of open hearths (Fig. 2a) (Popescu and Popescu 2016), with charcoal as fuel, which was added in consecutive layers [charcoal—iron ores—unslaked lime], and forcefully inserted air as a source of oxygen.The resulting 'ball lumps' (iron clumps that included slag) were reheated and …
An analysis of the geochemical distribution of selected trace metals among various geochemical phases of the sediments in the Oman Margin was carried out using …
The Arabian Peninsula as a whole is rich in metalliferous ores and minerals, especially in gold, lead and silver, and copper. In the North there are the copper deposits of Feinan and Timna (Hauptmann, 2000; Weisgerber, 2006); the Yemen also has many.There are many ore bodies in the Hedjaz Mountain range in the west of Saudi Arabia that are …
This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be …
