Most ore deposits are mined for the exploitation of metals. A metal is any chemical element (or elements in an alloy) having a characteristic luster, is opaque, and is a good conduc tor for heat and electricity. Approx imately 80 of our chemical elements are metals. Heavy metals have a density 5 g/cm3.

The possible two stages in the process of iron ore formation can be: 1.

Ore Wikipedia

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements.

Mining Efficiently in Minecraft dummies

Branch mining. Branch mining is effective because you can acquire a lot of ores efficiently. However, this type of mining consumes many tools because of the volume of stone you dig through, and produces much more cobblestone than valuables. Branch mining is a helpful method if you have patience, and a project in which you can invest your fortune of cobblestone.
