Suppose you wish to separate a mixture of fine particles of gold and sand, neither of which is soluble in water. If you add liquid mercury to the mixture, the sand will float to the top of the mixture while the gold will dissolve. The sand can then be skimmed from the surface. You can recover the gold by heating the solution toevaporate the liquid

Nov 26, 2012 There are many ways to extract iron ore from rock. Iron is magnetic so you could use a method that involves magnets, and it is also heavier than a lot of substances, so you could use a shaker and see which pieces weigh more. However, the way that we thought to separate iron ore
Mar 07, 2012 If you want to seperate iron from gold, all youd do is put a magnet over it and the iron would be attracted to it because its magnetic but the gold wont. Wiki User 2012-03-07 175802
Elemental sulphur and precipitated iron and arsenic compounds are separated from the leaching residue using physical separation methods, whereby the first intermediate is obtained, which contains gold- bearing sulphide minerals and gangue minerals as well as the gold that remains undissolved.
