Sublimation
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
The smell of naphthalene will likely be present in the mixture, although it may be less intense due to the dilution with chalk powder. The naphthalene odor may be detectable, especially in close proximity to the mixture.
a very simple and a common technique to separate them out is use a magnet. Since a magnet attracts iron , bring a strong magnet in front of the mixture and almost all of the iron powder gets separated
To separate gravel and earth powder, you can use a sieve or a screen. Pour the mixture onto the sieve and shake it gently to allow the smaller earth powder to pass through while the larger gravel remains on top. This physical process relies on the difference in particle size to separate the two.
When naphthalene and phenolphthalein dissolve in ethanol it creates a crystal-like powder. The powder will also appear to have a yellow tinge and has no smell.

To separate copper strips from sulfur powder, you can use a process called filtration. Mix the copper strips and sulfur powder with water to form a mixture. Then, pass the mixture through a filter paper to separate the solid copper strips from the sulfur powder, which will remain in the filter paper.

One common method to separate sulfur powder is by using a process called filtration. This involves passing a mixture of sulfur powder and a solvent through a filter, with the sulfur powder remaining on the filter while the solvent passes through. The collected sulfur powder can then be dried to obtain the separated solid.
The best process for separating powder from water depends on the powder. If the powder dissolves in the water, then boiling the water and condensing it (distillation), will separate the two components. If the powder does not dissolve in the water, then simple filtration will separate the two.

Table salt can be separated from a mixture of table salt and talcum powder through a process called filtration. In this process, the mixture is dissolved in water, allowing the salt to dissolve while the talcum powder remains insoluble. The mixture is then passed through a filter, which separates the insoluble talcum powder from the salt solution. The salt can then be recovered by evaporating the water, leaving behind the pure salt crystals.
Stir stones, chalk and water until the chalk is in suspension. Pour off the chalky water (repeat as required), leaving the heavier stones behind. Filter the chalky water to let clear water pass through, so leaving the chalk in the filter paper.
You can use a magnet to separate the iron fillings from the sulfur powder. The iron fillings will be attracted to the magnet, allowing you to easily separate them from the sulfur powder.
