emissions. Titanomagnetite-type iron sand is an important alternative source of iron minerals for coun-tries with long coastlines. Thus, the process of making iron through direct reduction and using iron sand as the main raw material becomes an environmentally friendly solution, especially for countries that do not have primary iron ore reserves.
Iron Making | New Zealand Steel
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 ...

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.
To Choose the Right Sand Additive, Understand Composition, Effects
Iron oxides have been used for many years and are typically some form of red iron oxide, black iron oxide, or sometimes a blend. They act as a flux to promote softening of the sand, which can absorb more thermal stress before a crack in the core/mold occurs. Being oxygen-rich, iron oxides also can tie up some gasses during the casting process.

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.
