How to process iron ore
The obtained iron powder is sent to a dryer for drying to obtain iron fine powder. Australia, Brazil, China, India, Russia, South Africa and Canada are all countries with rich iron ore resources in the world. These regions are home to large iron ore deposits and provide the majority of the world's iron ore supply.

Iron Casting Processes
A typical recipe would be: Sand Mixture: silica sand (SiO2), chromite sand (FeCr2O4), or zircon sand (ZrSiO4), 75 to 85%, sometimes with a proportion of olivine, staurolite, or graphite. Bentonite clay (primary binder): 7 to 13%. Water : 2 to 4%. There are many Green Sand recipes that vary the proportion of clay, water and sand grains, but they ...

How manhole cover is made
Besides iron, the other raw material required to make manhole covers is green sand, which is sand bound together with clay. The green sand is used to produce the molds into which the molten iron is poured. The sand mixture consists of about 90% silica sand, 4-10% clay, 2-10% organics (e.g., coal), and 2-5% water.

Iron Making. Along with coal and limestone, the primary concentrate (ironsand) is heated and dried in one of four multi-hearth furnaces. It is then fed into the four reduction kilns, where it is converted to 80% metallic iron. Two melters then convert this into molten iron. The iron, at around 1480°C, is transferred to the Vanadium Recovery ...

Iron Making: Casting
Gray iron was also cast in the sand to make firebacks. When poured into the molds, it was necessary to separate the slag from the iron to keep the slag from being trapped in the iron. Cookware was finished by filing and cleaning before it was brought to the river for shipment. Mottled iron was also cast into the sand in the shape of long bars.

Iron- and Steel-Making Process | SpringerLink
Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (55–60%)-rich ore is usually used.
