Potash is an imprecise term. If you mean the ashes from a fire, then, usually, yes. If you mean the potassium content of a potassium compound such as potassium carbonate or potassium chloride (as the term is used when discussing fertilizer), it depends on the particular compound. Potassium chloride is among the substances often mined, and other compounds can be made from it.
