Is there enough iron on the Moon to support industry?

Iron in combination with other elements will require some form of mineral processing to liberate the iron. The lateral extent of iron on the Maria of the Moon is large. One of the main things that will determine the viability of an iron extractive industry on the Moon will be the depth of the iron rich deposits.

Where Can Iron Be Found?

Iron can be found in the Earth's core, in the Earth's crust, in hemoglobin, in steel and in magnets. It is rare to find iron in its elemental form on Earth, but it has been found in igneous rocks in Russia. Iron is a shiny gray metal. When it oxidizes, the resulting compound is known as iron oxide or rust. Iron rusts in damp air but not in dry air.
