Jan 27, 2021 · That done, find another Iron Ore patch, and get that set up too - but this time, you're not smelting Iron Ingots, you're smelting Magnets. Magnets take 1.5s instead of 1s to smelt, so you'll need 9 Smelters instead of 6 to make a full belt, and about 11 Turbines to keep it all powered

how iron is made - material, manufacture, making, history

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts

Iron ore is mixed with coke (from super-heated metallurgical coal) in a blast furnace. Air that has been heated to around 1,200 degrees Celsius is injected into the furnace, creating a flame temperature of 2,000 degrees. This converts the iron ore to molten pig iron and slag. Then, impurities are removed and alloying elements are added
