It is initially done manually. In that you pick out the gold from the other rocks. After that there are various acids and chemicals that dissolve the gold and separate it from the other material
Crude oil is made out of hydro-carbons which causes the oil to separate out in a particular oil. The different fractions of carbons work independently from each other.

no
yes you can distillate the chemical. Abean xxx
separate chemicals substanses from each other
filter paper
Probably but you wouldn't want to because separated Chlorine and Sodium are poisonous.
It depends on the chemicals you're trying to separate--it could be anything from a magnet (if you've got iron filings mixed with other powders) to water and filter paper, to a distillation unit.

The toxic heavy metal, mercury is frequently used to separate out the gold.
