			==Biomining from Ash==
			[[Biomining]] is sometimes performed on ash. A plant that is known to concentrate the mineral of interest is first grown on low-grade ore. It is then burned, thereby concentrating the mineral. Bioleaching is then performed on the ash, using special microbes.

	==Extraction of minerals==		==Extraction of minerals==
	Wood ash contains ~~some useful~~ minerals that can be separated out. ~~Among them~~ is calcium carbonate ~~as the major component~~, representing 25 or even 45 percent (depending on feedstock and burn conditions). Less than 10 percent is potash, and less than 1 percent phosphate; there are trace elements of iron, manganese, zinc, copper and some heavy metals. However, these numbers vary, as combustion temperature is an important variable in determining wood ash composition. All of these are, primarily, in the form of oxides.

	* calcium carbonate
	* sodium carbonate

			Here is a brief protocol via [[Caveman Chemistry]]:

			''If we add the ashes to water, the soluble potassium and sodium salts will dissolve while the insoluble silica and calcium carbonate will settle to the bottom. We can then drain off the water (containing the "good stuff") and throw the insoluble material away. To separate the chlorides from the soluble carbonates, we will exploit the greater solubility of the carbonates in hot water. We will bring the liquid to a boil and continue boiling until enough water boils away for an insoluble precipitate to form. This is very likely a mixture of sodium and potassium chloride. From this point, we will continue boiling until half of the remaining water is removed.''

			''At this point we can be reasonably certain that only the soluble carbonates remain in solution. We will carefully pour off the hot liquid into another container, leaving the solid material behind. As the liquid cools to room temperature, the less soluble sodium carbonate will precipitate leaving the more soluble potassium carbonate in solution. Finally, the remaining solution can be drained off and boiled to dryness, producing solid potassium carbonate.
			''

			''One of the observations you make should be that it takes a lot of wood to make a little ash and a lot of ash to make a little potash. Thus, while it is not particularly difficult to extract potash from wood, you will go through an enormous amount of wood to produce commercial amounts (pounds and tons) of potash.
