calcium | Definition, Properties, & Compounds | Britannica
Occurrence, properties, and uses Calcium does not occur naturally in the free state, but compounds of the element are widely distributed. One calcium compound, lime (calcium oxide, CaO) was extensively used by the ancients.The silvery, rather soft, lightweight metal itself was first isolated (1808) by Sir Humphry Davy after distilling mercury from an amalgam formed by electrolyzing a mixture
iron ore contains calcium
Iron Ore (Fe) Minerals Deposits in Nigeria - States, and Uses. Iron ore contains four main types of iron oxides deposits solely dependent on the mineralogy and geology of the ore deposits, these includes magnetite, titanomagnetite, hematite and pisolitic ironstone, out of the four the two most important minerals deposits are hematite (Fe2O3) and magnetite (Fe3O4).

Any ore must contain enough of the metal to make it worthwhile to mine and then extract the metal. High grade ores will therefore be the most economical to exploit BUT over time the better quality–richer sources will decrease, especially with the power of the global economy and powerful and growing economies of Brazil, China, India and other Asian economies.
