Steel Ingot - Official Satisfactory Wiki

Solid Steel is the most efficient recipe, due to conserving Coal which is the rarer component and allowing for the incorporation with a ratio of Iron Ore to ingot greater than 1:1. If a large Iron Ingot pipeline is already established, a Solid Steel foundry can draw from that rather than requiring a separate ore stream.

Iron Ores | Encyclopedia

The chemical bonding of elements is a process quite different from mixing, and a compound is not to be confused with a mixture, whose composition is highly variable. Another way of putting this is to say that all minerals must have a definite chemical formula, which is not possible with a mixture such as dirt or glass.
