How can I dig a lot of iron ore in my world?

Iron ore is a common resource in my world, but its quantity is less than coal. It may not be easy for beginners to find iron ore. The following is a detailed method analysis. In fact, there are some better ways to obtain iron ore.

Iron ore procurement method:

Iron ore is underground (this is nonsense). If the house extends downward, as long as you dig the mine down to 10 (unless your house is on an 80-high cliff), there must be iron ore around it.

Iron ore appears below 63. If you don't know the coordinates, you can press F3 to view them. Most of them are under 40, but none of them is over 64.

After iron ore is obtained, it is thrown into a furnace and burned to obtain iron.

Relatively speaking, iron is not rare, although it is much less than coal, but it is also a common resource.

If you are in a village, you can build more houses (houses must have doors, walls and roofs) for villagers to breed.
