Can't Seem to Find Iron
And then comes iron - and it's a completely different beast. All of the iron ores, to some extend, but especially magnetite. You see, to generate ores, the game rolls a number of tries each chunk. It picks a random block within the ore's spawn range in that chunk, and rolls a die against the spawn chance in that location.

Quality requirements of iron ore for iron production
The integrated iron- and steelmaking route involves blast furnace (BF) ironmaking followed by basic oxygen steelmaking (BOS). The BF uses sinter, pellet, and lump ore as the iron-bearing raw materials and coke and pulverized coal as reducing agents to produce hot metal with consistent quality for the BOS process.
