Detection of the assimilation characteristics of iron

2020-1-14  Resistance in iron ore undergoes a sharp change of up to several orders of magnitude when the sintered solid phase changes to liquid phase. In view of the insufficiency of existing assimilation detection methods, a timing-of-assimilation reaction is proposed, which was judged by continuously detecting the changes in resistance at the reaction interface.

What is Iron Ore? (with pictures) - Info Bloom

Iron ore is any rock or mineral from which iron can economically be extracted. It comes in a variety of colors, including dark gray, bright yellow, deep purple, and rusty red. The iron comes in the form of iron oxides such as magnetite, hematite, limonite, goethite, or siderite. Economically viable forms of ore contain between 25% and 60% iron.
