How can mixtures of solids be separated?

Here are some ways to separate mixtures of solids By appearance Use tweezers to separate one type of solid from another By size Use a sieve with holes of the appropriate size The smaller particles will pass through and the larger particles remain in the sieve By winnowing Wind throws lighter particles further than heavier particles By magnetism You can use a magnet to separate iron Get price

How to Separate a Mixture of Sugar Water

20/04/2018The easiest way to separate a mixture of sugar and water is to use distillation a process that separates substances based on their different boiling points Sugar does not boil but the point at which it crystallizes (320 degrees Fahrenheit) is much higher than the boiling point of water (212 degrees Fahrenheit) so when you boil a mixture of sugar and water the water turns to steam and Get price
