Wood or charcoal fires and lots of forced air from bellows can heat ore above the melting point of iron (1811°C) .
Well, isn't that a happy little question! To separate charcoal powder and iron fillings, you can use a process called magnetic separation. Since iron is attracted to magnets but charcoal is not, you can use a magnet to easily separate the two materials. Just like that, you'll have your charcoal powder and iron fillings separated in no time at all!
Well, honey, to separate charcoal powder and iron fillings, you can use a little technique called magnetic separation. Just grab a magnet, wave it over the mixture, and watch as those pesky iron fillings cling to the magnet while the charcoal powder minds its own business. Easy peasy lemon squeezy!
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Yes, iron has a much higher melting point than room temperature. Room temperature is typically around 20-25 degrees Celsius, while iron has a melting point of 1538 degrees Celsius.

Iron ore was mixed with limestone and charcoal. The charcoal would be ignited, and air forced through the mix. The charcoal would removed the oxygen from the iron ore, leaving iron.

Charcoal is important for smelting iron because it provides the high temperatures needed to melt the iron ore and extract the metal. Charcoal also acts as a reducing agent, helping to remove oxygen from the iron ore to produce molten iron. In addition, charcoal burns cleaner and hotter than wood, making it more efficient for smelting.

The melting point of iron (nanopowder or not) is 1 538 0C.
In a charcoal iron, the energy conversion involves the chemical energy stored in charcoal being converted into thermal energy through combustion. This thermal energy is then used to heat up the metal plate of the iron, which in turn transfers heat to the fabric to remove wrinkles.
Melting of any element, including iron, is a physical change. Melting is just a transition between states of matter, from solid to liquid. The solid state of iron can be regained if the liquid iron is cooled; so this denotes a physical change. There is no change to the chemical composition of iron during melting.
