Unsmelting steel and bronze is both possible irl bronze is easy to unsmelt. This is easy because the melting point of bronze and tin differ a lot -> (copper 1085 °C/1985 °F , tin 232 °C/450 °F) so if you would heat bronze to any temperature between  232 °C/450 °F and  1085 °C/1985 °F the tin would melt and slowly segregate. On the other hand making iron from steel is a lot harder. This is only possible by burning away the material that the iron got alloyed with (in our case for instance coal or sarluin) this is very hard because you need to keep the iron from oxidizing along with the carbon or other stuff that lotr dudes make steel of.
