ABSTRACT:
A method for the preparation of organic chelates utilized as ingredients of animal feedstuffs. The organic chelates are passed to the intestines of livestock without decomposition in the stomach, and thereby have a high absorption rate. The present invention provides a preparation method of perfect chelate minerals having a high yield and containing copper, zinc, iron, manganese, or cobalt. The organic chelate mineral is prepared by precipitating metal sulfates or chlorides with sodium hydroxide or potassium hydroxide in a solution of two equivalents of an amino acid completely dissolved at above 70° C., collecting metal hydroxide by removing sodium sulfate, potassium sulfate, sodium chloride or potassium chloride through filtering, dissolving the metal hydroxide by adding the equivalent weights of hydrochloric acid, and then neutralizing the hydrochloric acid added for dissolving metal hydroxide.
