Generally yes. Smelting is used to separate raw ores into their component pieces to extract the pure metal, and in most cases this will involve chemical reactions of some form.

Is ice melting at 0 degrees Celsius a chemical property?
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
Why is the change from iron to rust considered a chemical change?
The reason that rust is considered a chemical change is because the "connections" or the bonds of atoms are changed in the process. When atoms "rearrange themselves" by changing the "connections" or bonds to allow different compounds to be formed, as is the case with the formation of rust, a chemical change has taken place. In iron, the iron atoms are arranged in a metallic crystalline matrix. When rust occurs, oxygen bonds to the iron atoms (which where not chemically bonded to anything before) to create an oxide of iron.
Is a piece of ice melting and reacting with sodium a physical or chemical change?
The melting of ice is a physical change, as it changes from solid to liquid without altering its chemical composition. However, when the melted ice reacts with sodium to form a new compound, it is a chemical change because the chemical composition of the substances involved is altered.
When a mixture of iron and sulfur are heateda compound called iron sulphide is producedwhat type of change is this?
This is a chemical change because a new substance, iron sulfide, is formed with different properties compared to its original components, iron and sulfur.
Which one is a chemical change rusting of iron or melting of iron?
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.
Is an iron nail melting a chemical change?
No.
Is melting iron physical change or physical property or chemical change or chemical property?
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.
Which one is a chemical change -rusting of iron or melting of iron?
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
Is melting iron is a or physical change?
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.
Is iron melting a physical change?
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
Is melting iron into liquid a chemical change?
Yes, melting iron into a liquid state is a physical change, not a chemical change. This process involves applying heat to change the state of the iron from solid to liquid, without altering its chemical composition.
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Is Iron melts at 1535 degrees a chemical change?
No, the melting of iron at 1535 degrees Celsius is a physical change. A chemical change would involve a rearrangement of the atoms in the iron, leading to the formation of a different substance.
Why is melting of butter is a physical change whereas rusting of almirah is a chemical change?
Melting of butter is a physical change because it involves a change in state from solid to liquid without altering the chemical composition of the butter. Rusting of an almirah is a chemical change because it involves a reaction between iron in the almirah and oxygen in the air to form a new substance, iron oxide, which has different properties than the original iron material.
Is melting a iron rod a physical change?
Melting an iron rod is a physical change
Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
Iron rusting is a chemical change since it involves the formation of new substances due to a chemical reaction between iron and oxygen. Copper melting, water freezing, and gas condensing are physical changes where the substances may change state but do not form new chemical compounds.
