Abstract: This invention relates to improvements and methods of beneficiation of uric acid and primary salts of uric acid. The compounds are obtained by treating fowl excrement or waste material by means of first promptly collecting the waste material; removing the moisture therefrom, and then subsequently grinding and fractionating this material according to particle size. The method results in fractions of the original waste material which have increased concentrations of uric acid. The enrichment in uric acid concentration results in a material which is very suitable for final removal and treatment of the contained uric acid. A process for the extraction of high purity uric acid and primary salts of uric acid from the pretreated waste is also disclosed. The invention includes the utilization of the drying and sieving process of the waste material to obtain portions from the original product which is suitable for animal feed and supplements.
