During the process of steel production the flaws in the steel casting are detected by ultrasonic vibrations.
There's a fundamental problem with the question. Iron is not a "mineral" in the usual sense of the word. Elemental iron is too reactive to be found in nature as a mineral. Leaving that aside... Steel is not "iron". It's mostly iron, with a small admixture of other stuff. So it's not the same as elemental iron, but it's pretty close.
Bare steel + moisture + oxygen = rust. Paint provides a barrier to shield the steel from moisture and oxygen.

You would first paint a solid color that is the back ground of the wood you want to imitate. Use a good exterior paint. Then, add the grain with a different color(s).
Magenta
Plaster, mortar, glass production, steel production, water and sewage treatment, pottery, paint, etc.
Iron ore. Bessemer figured out that shooting air into the molten iron would remove the impurities and that made steel.
You are going to find them in stainless steel silver color. As they are made with stainless steel, this is the only natural color unless you choose to paint the fence.
