List of Common Magnetic Rocks & Minerals (with Explanation)
Some rocks are magnetic because of the presence of iron or iron-bearing minerals. The higher the concentration of magnetite (the main magnetic mineral), the stronger the magnetic properties of the rock. Ironstone — sedimentary rock with the highest concentration of iron oxides is the most magnetic. Before moving further, let's …

As Earth began to take shape about 4.5 billion years ago, iron and nickel quickly separated from other rocks and minerals to form the core of the new planet. ... and pyroxene. The other major type of rock found in the mantle is magnesium oxide. Other mantle elements include iron, aluminum, calcium, sodium, and potassium.
Iron
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks ...

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite.Hematite is also known as "natural ore".
