Say you have separated your non-polar solvent (like xylene) from the rest of the mimosa liquid.. To salt out means to mix that solvent with some acidic solution (like, say, vinegar). The alkaloids will turn into salt form (thats why we call "salting out" ), and hence will move from the non-polar solvent to the acidic solution. Its basically like doing a pull, but in reverse, in which you will keep the acidic solution and not the solvent. Do this 3x, put the acidic solution together, and evaporate that. If its vinegar you used, you'll have a goo once its all evaporated. Mix that with sodium carb and a bit of water, let it dry, and pull with IPA/Acetone.
There are other a bit more "advanced" ways of salting out (Actually very simple process), like adding FASA to xylene or FASI to limonene, and your alkaloids will precipitate as fumarate crystals straight out of the solvent.. Then you can convert your fumarate to freebase.
Check BLAB tek, AmorFati tek and Q21Q21's tek in our wiki, it describes more of this process.
