How to recover iron from rust?
Rust is basically Fe2O3 (or Fe2O3•H2O), and to recover the iron, it is necessary to remove the oxygen from the compound. This is usually done by introducing carbon – normally in the form of CO gas – to reduce the oxygen in the Fe2O3:
What is a crucible for melting steel?
A crucible or pot for melting steel may have a metal exterior, used for its mechanical properties, and mounted to the handling equipment, but the inside of the pot is lined with a refractory material. A refractory material is simply something that is very resistant to heat. In more ancient times, this was usually clay that had been carefully prepared to drive out all the water, but in more recent times other materials that are ceramics or glasses have also been used. This protective material has an extremely high melting point, substantially higher than the melting point of the metal. Most are also good insulators, or else some insulation is also installed behind the refractory material. This keeps the heat at the metal outer shell cool enough that its mechanical properties to not degrade too much (they design the outer shell to perform at whatever temperature it reaches, so at room temperature it might be considerably stronger than what is needed, but at working temperature it is not at risk of failure.)
How much aluminum will replace steel?
Also, note the density of aluminum is very low about 35% of steel so one lb of aluminum will replace the same size part as nearly 3 pounds of steel.
Is rust a metal?
Yes. There is only one metal we’re talking about when referring to rust and that is iron. Rust is iron oxide, specifically hydrated Fe2O3. Almost all iron production throughout the ages is based on separating iron-oxygen bonds by using lots of energy. All types of steel making and steel recycling furnaces, from the oldest charcoal hearth finery to the latest electric arc furnace turn iron oxides into some non-oxidized form of iron.
Can iron be melted?
In general, not melted, but smelted again. Take iron, as an example, iron— if it rusts goes into an oxide like Fe2O3. It either came from an red oxide like that or a black oxide like Fe3O4. Either way the oxide can be reduced into iron by heating it with carbon, to combine with the oxygen leaving metallic molten iron. Careful! It’ll be hot coming out.

Does smelting metals mean melting?
I should add that smelting doesn't just mean melting. In order to actually break up the metal oxide or metal sulfide in the ore, you'll need a chemical catalyst as well. The catalyst steals the oxygen, because it has a higher binding energy at high temperatures, leaving a slag and a pure metal. For a metal like hematite (iron oxide), I believe carbon is a popular catalyst.
Can a catalyst change during a reaction?
A catalyst doesn't change during a reaction. If it took oxygen it couldn't be a catalyst.
