Kiruna-type iron oxide–apatite (IOA) deposits, an important global resource of iron and potentially rare earth elements (REEs) and phosphorus, consist of massive, disseminated, brecciated, and/or vein-type magnetite + apatite + diopside and/or actinolite ores (1–6).It has long been recognized that IOA deposits are spatially and temporally …
Iron is a major component of hemoglobin, a type of protein in red blood cells that carries oxygen from your lungs to all parts of the body. Without enough iron, there aren't enough red blood cells to transport oxygen, which leads to fatigue. Iron is also part of myoglobin, a protein that carries and stores oxygen specifically in muscle tissues.

Not all iron or steel is magnetic. There are even some nonmetals that display magnetism! Here is a review of the types of magnetism, a list of magnetic materials, and a look at metals that aren't magnetic. Types of Magnetism. In order to understand which metals are magnetic, it's helpful to review the five types of magnetism:
The cast iron is obtained by re-melting pig iron with coke and limestone in a furnace known as a cupola. It is an alloy of iron and carbon. The carbon contents in cast iron differ from 1.7% to 4.5%.
