One method is to use a magnet to separate the iron fillings from the sulfur powder, as iron is magnetic but sulfur is not. Another method is to mix the mixture with a solvent that dissolves the sulfur powder, leaving the iron fillings behind. Lastly, heating the mixture can also cause the sulfur to sublimate, leaving the iron fillings behind.
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.
