Iron ore
What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.

Where Does Iron Come From or How Is It Made? | Sciencing
Most of the iron mined for human use winds up in the form of steel. "Steel" is an alloy, meaning a mixture of metals. A popular form of this product today is called carbon steel, which is somewhat misleading because carbon contributes only a tiny fraction of the mass of this steel in all its forms. In the highest-carbon form of carbon steel ...
Iron Ore
Iron ore is a mineral block found underground. It is a source of raw iron, which can be smelted into iron ingots. Deepslate iron ore is a variant of iron ore that may generate in deepslate and tuff blobs. Iron ore itself can be obtained by mining it with a stone pickaxe or higher enchanted with Silk Touch.

What Is the Origin of Iron?
Iron continued as the key metal fabric in human civilization until the 1850s, when innovators began to learn that if a bit more carbon was added to iron during the production process, a durable yet flexible metal resulted. By the 1870s, production innovations made this new metal alloy called steel more economically viable to mass produce. ...
