Hydrogen can serve as a reducing agent and the most prominent appliion appears to to be iron ore reduction. A variety of direct reduction of iron ores without coke has been carefully studied for a long time. These use hydrogen, carbonmonoxide and carbon in a combination. The reason for the development is due to the following: (1)
When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestoslike mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul Campbell, 2011).
Iron ore. Iron doesn''t occur naturally. Being highly reactive, it combines easily with other minerals to form ores. Those with the highest iron content are found near the surface of the earth and are relatively easy to mine. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). Most iron ore is extracted through opencast mines.
· Corrosion is a costly problem. But by understanding its root causes, effective steps can be taken to prevent and combat it. Iron ore and corrosion Iron ore is a combination of minerals from which metallic iron can be extracted. Corrosion is the reverse process of metallurgy. In other words, the energy used to transform natural . Continued

Ramesh Singh, in Applied Welding Engineering (Second Edition), 2016. Smelting. Smelting is an energyintensive process used to refine an ore into usable metal. Most ore deposits contain metals in the reacted or combined form. Magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (αFeO[OH]), limonite (the generic formula for limonite is FeO[OH].nH 2 O), and siderite (FeCO 3) are iron ores, and ...
· Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
