Will surface rust on an iron crucible be converted if used to melt aluminium?
Can one convert bog/lake iron ore into iron using molten aluminium similar to the Thermite reaction?
Or perhaps the real question is what temperature would this occur at?
EDIT: I'm hoping one could use the molten aluminium instead of aluminium dust to achieve the same reaction as occurs in the Thermite process. I know about Thermite steel rail and copper earth connection welding. My goal is to reduce rust to iron by sprinkling it (with attendant sparks) onto a molten aluminium surface. Will the temperature be too low in practice or will the iron oxidise or blow off before consolidating? Trials today were inconclusive due to low temperature and small sample size.
