ABSTRACT:
A process for producing an animal feed and a fertilizer ingredient from animal manure which comprises acid solution and either wet or dry manure. The essentially basic minerals contained in the manure chemically react with the acid to form soluble salts. The acid and essentially basic minerals are used in an amount so that there is an equal molar reaction basis and so that sterilization of the manure is achieved. A slurry containing various solid fractions and an acid-water fraction is formed. The various fractions, each separated from each other, are recovered from the slurry.
