you an use a magnet to get the iron fillings out
You need a magnet to separate iron from a mixture (not from a compound).
Yes, the reaction is possible when the mixture is heated.
No, the proportion of iron and sulfur in a mixture is not always fixed. It depends on the specific composition of the mixture and how it was prepared. Different mixtures can have varying ratios of iron and sulfur based on their intended use or source.
Iron is a chemical element with the symbol Fe, while iron sulfide is a compound made up of iron and sulfur with the chemical formula FeS. Iron is a pure metal, while iron sulfide is a chemical compound that forms when iron reacts with sulfur. Iron sulfide is often found in nature as the mineral pyrite, also known as "fool's gold."

its the same...... bar the fact that in iron sulphite the 2 chemicals have compouded were as iron and sulphur is still a mixture
To obtain sulphur from a mixture of sulphur and iron fillings, you can use a magnet to separate the iron fillings from the mixture. Then, you can heat the remaining mixture to sublimate the sulphur, which will turn into a gas and can be collected by condensing it back into a solid form.
iron starts melting

If you just mix iron and sulphur together, you're still left with a pile of iron and sulphur that are distinctly separate and could be easily separated by throwing the mixture in water (iron sinks, sulphur powder floats). If they were to react together, to become iron sulphide, then they would be chemically bound to each other as a compound and wouldn't be able to be separated by physical means.

The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
Attract it with a magnet or dissolve sulphur in carbon disulfide (CS2), though this is the most 'stinky' way (and toxic! and explosive!).
When you mix Iron filings and Sulphur crystals together, you form a mixture of Iron and Sulphur from which both the components can be separated by physical means. But if you heat the mixture strongly, then it becomes a compound of Iron Sulphide from which the two components cannot be separated by physical means.
ironchloride and sulphuric acid
The iron in the mixture will be attracted to the magnet and stick to it. Sulfur, being non-magnetic, will not be affected by the magnet and will remain in the mixture. This can be used to separate the iron from the sulfur.
