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
Just use a magnet.
A magnet will attract the iron leaving the coffee behind. It is also possible to separate them by flotation on water; add some detergent to the water to break the surface tension so the iron powder can sink while the coffee powder floats.
1. Salt will dissolve in carbon disulphide 2. Now we have a mixture of iron filings sugar and carbon disulphide(salt dissolved in it) 3. Separate iron filings by magnet. 4. Remove the sugar by Decantation process. 5. Separate carbon disulphide and salt by distilation.
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
Salt is soluble in water.Sulfur is soluble in carbon disulfide.Sand is insoluble.
Iron powder is not soluble in water.
Iron powder is attracted by a magnet, sulfur is dissolved in carbon disulfide, but be careful: it is explosive, toxic and stinks (rotten cauliflower)
Use a magnet to remove the iron filings. Filter the remainder to separate the insoluble chalk powder from the water. Wash and dry the iron filings as they will be contaminated. Dry the chalk powder to remove traces of water.
yes it is hard though

get a magnet that attracts iron
you use a magent
Use a magnet to lift out the iron filings.
1. Salt will dissolve in carbon disulphide 2. Now we have a mixture of iron filings sugar and carbon disulphide(salt dissolved in it) 3. Separate iron filings by magnet. 4. Remove the sugar by Decantation process. 5. Separate carbon disulphide and salt by distilation.
Carbon disulfide can be used to separate a mixture of iron filings and sulfur. This is because carbon disulfide can be used to dissolve sulfur, thus leaving you with the iron filings.
Iron can be extracted with a magnet (if you think to nail=fastener).
i want it
by using carbon disulphide
