Production of organic compounds of trace elements, e.g. zinc methionate for use as animal feed additive, involves the solid-state reaction of a metal oxide and a solid organic acid in a pulveriser, e.g. a vibration grinding mill

摘要

A method for the production of organic compounds of trace elements involves subjecting any dry mixture of an inorganic metal oxide and a solid organic acid to impact and pressure in a pulveriser so that the enthalpy released induces a solid-state reaction to form a metal salt-like compound.
