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.

Depends on the alloy. Steel at its simplest is just a mix of iron with a bit of carbon
Silica, in the form of quartz, is a nonmetallic mineral commonly used in building materials and in the manufacture of steel. It is a key component in concrete, glass, and ceramics, as well as being used as a flux in steel production to lower the melting point of the raw materials.
