How can soilds be separated using evaporation?

Answer 1

separated from a liquid?

Heat them, the liquid will evaporate, the solids will not

further. Yes indeed. In the manufacture of table and commercial salt from salt ponds, after evaporation has proceeded so far, the liquor is decanted, and the remainder is further evaporated.

The magnesium salts have a different solubility to the sodium ones, and this is how that process works.

During the evaporation process, various bacteria find the new salinity to their liking, and the colour of the ponds alters according to the bacteria. Beautiful colours from greens, reds, yellows.

Answer 2

Solids can be separated using evaporation by first dissolving the solid in a liquid (like water), then heating the solution until the liquid evaporates, leaving behind the solid. The solid can then be collected and further dried if necessary.
