describe one of the processes that could be use to separate a mixture of iron filings, wood shavings, and salt

Answer 1

You could buy a JML Iron/Wood/Salt Separator. They are available from Woolworths, Poundstretcher and Wilkingsons and are £9.99 each.

Answer 2

First you use a magnet to separate the iron fillings from the wood shavings and salt. Next take the remaining wood/salt mixture and put into a container of water, stir for a few minutes and the salt will dissolve leaving only the wood shavings floating in the water. Drain the water from the wood shavings and then boil the water. As the water comes to a boil it will evoporate leaving behind the salt.

Answer 3

The very best way would be to use water: the iron filings would sink; the wood shavings would float and the salt would dissolve. You would then skim the wood shavings from the surface of the water, then you would pour the water through cheese cloth into another vessel so that you could catch the iron filings, you would then boil the water to precipitate out the salt.

Answer 4

Use a magnet to attract the iron. Put the wood shavings and salt in water, skim the wood off and let the water evaporate.

Answer 5

use a magnet to get the iron shavings first, then put the wood and salt into a shallow pan or plate, and shake in a gentle circular motion, as if panning for gold, the heavy wood shavings should seperate from the salt.

Answer 6

Magnet and water should do the trick - though you'll then have to use heat to separate the salt from the h20.
