摘要: Methods treat ash from waste incineration, wherein the methods at least comprise: a) the digestion of the ash by a leaching liquor containing phosphate ions in solution such as to form a first solid phase comprising impurities and a first liquid phase comprising phosphate ions; and b) the separation of said first liquid phase comprising phosphate ions from said first solid phase. Step a) is carried out for a duration of less than one hour or at a temperature of more than 40° C.
