How does the separation method of separating mixtures work?

• using a magnet to attract particles

• sorting material based on observable characteristics

• pouring the mixture through a filter

• evaporating the liquid

• by floating to the top

• by evaporating

• by settling to the bottom

• by pouring through a filter

How are lighter materials separated using a liquid?
