Compounds need to be separated with chemical means such as heating.
Mixtures can be separated with physical means such as by hand.
I hope I helped! :)

there are hundred's of different types of separation... It all depends on what you want to SEPARATE!!!? let me give u an example, if u have a bag with 2 types of marbles .... one of them weigh 1 gram, the other weigh 10 grams... as u notice, the heavy one will have a different force, different attraction level, momentum, etc.... if u throw the bag out with enough Same force, the smaller one will go faster and farther... (u just separate them by Size)..
example # 2, if a substance in a mixture is different base on (polarity) .. u can easily separate it by using a polar solven to extract it out, or a non-polar solvent to extract the other one out...
anyway, there are tons of ways u can separate a thing!! the key is... WHAT are the things (in a mixture) that are different, (size?? polarity??? affinity??? attraction?? electrostatic attration?? etc) after u know what is different, use that FACT to separate them by using high-tech instrument!!!

substances in a mixture can be physically separated. For instance, you could separate rocks from salt by placing them in water so the salt dissolves.
substances in a compound must be chemically separated. the mercury in mercurous oxide can be separated by heat.

different mixtures can be separated different ways, Suspensions can be by settleing and filtering. Solutions bt distillation and chromatography.
A compund can only be separated by chemical means which means a chemical reaction is required.
