Extraction of metals
-
-
-
-
Iron produced flows to the bottom of the furnace where it is intercepted to the bottom part, where it fuses
-
-
-
-
-
-
- oxygen enters to form molten steel
-
-
-
-
- Lime is added to from slag
-
-
Sulfur and sulfuric acid
-
-
- surfur is burnt into sulfur dioxide
-
- gasses are mixed and cleaned by electrostatic precipitation
-
-
- SO₃ is dissolved in Sulfur
- then it's dissolved in water
- Finally the concentrated sulfuric acid is diluted when needed
-
Haber Process
-
- nitrogen and hydrogen are compressed to 200 atmospheres
- then they pass over a series of catalist beds
-
15% of it all becomes ammonia, the rest passes though the bed and are heated again

Recycling metals
-
Recycling alluminium
expensive to extract, so it's recycled
-
Recycling steel
ceaper to recycle, but not much
