Coal is used as fuel in blast furnaces, steam boilers, steam locomotives, domestic cooking purposes etc...
After use, the remaining sediment is ash. So coal cannot be
recycled.
Zinc, Allumimium,and iron are metals, and irrespective of whichever use it is put, it can be repurified and recycled into any other items. Only a small fraction is in the recycling process.

I've used recycled zinc, aluminium and iron.
Coal you could actually recycle by collecting the CO2 and reforming it, but it would take more energy to do so than the energy it put out in the first place.
