Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced.
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.
In the iron and steel industry, direct reduction is a set of processes for obtaining iron from iron ore, by reducing iron oxides without melting the metal. The resulting product is pre-reduced iron ore. Historically, direct reduction was used to obtain a mix of iron and slag called a bloom in a bloomery.
Spinach is not a particularly good source of dietary iron. While it does contain more iron than many vegetables such as asparagus, Swiss chard, kale, or arugula, it contains only about one-third to one-fifth of the iron in lima beans, chickpeas, apricots, or wheat germ.
Injectable forms include iron dextran and iron sucrose. [13] They work by providing the iron needed for making red blood cells. [14] Iron pills have been used medically since at least 1681, with an easy-to-use formulation being created in 1832 using Chicken Liver extracts and majority from plants. [15]
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.
Geritol is a United States trademarked name for various dietary supplements, past and present. [1] Geritol is a brand name for several vitamin complexes plus iron or multimineral products in both liquid form and tablets containing from 9.5 to 18 mg of iron per daily dose. [2] The name conveys a connection with aging, as in "geriatric." The ...
The research group distributed an iron disc to women in the village, asking them to place the disc in their pot while making soup or boiling water. The women were reluctant to use the chunk of iron while cooking, and "almost no one used it". [7] Charles stated that it was a "challenge in social marketing". [8]
