Direct reduction processes can be divided roughly into two categories: gas-based and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.) in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
Another factor was that mold and fungus in the grains, which led to several diseases, were significantly reduced in the processing that resulted in white flour. In the 1920s, Benjamin R. Jacobs began to document the loss of essential nutrients, however, through this processing of cereals and grains and to demonstrate a method by which the end ...
Flour loses nutritional value due to the way grains are processed; enriched flour has iron, folic acid, niacin, riboflavin, and thiamine added back to it. Conversely, other fortified foods have micronutrients added to them that don't naturally occur in those substances. An example of this is orange juice, which often is sold with added calcium. [4]
Experts say that even some plant-based meat alternatives may have unhealthy levels of heme iron added, along with other processed ingredients. ... all the ways they consumed iron, from food to ...

White beans. There’s a reason beans are a go-to for plant-based eaters. One half-cup of white beans offers nearly 3.5 mg of iron, the USDA says, along with 8.7 grams (g) of protein and 5.6 g of ...
Plants for the production of pre-reduced iron ore are known as direct reduction plants. The principle involves exposing iron ore to the reducing action of a high-temperature gas (around 1000 °C). This gas is composed of carbon monoxide and dihydrogen, the proportions of which depend on the production process.
Elemental iron, or reduced iron, despite being absorbed at only one-third to two-thirds the efficiency (relative to iron sulfate), [165] is often added to foods such as breakfast cereals or enriched wheat flour.
