NUTRITION PRODUCT, PARTICULARLY FOR ANIMALS AND SOILS, METHOD AND PLANT FOR MANUFACTURING SUCH PRODUCT

摘要

A nutritional product for animals and for soils consists of aggregates of organic sea limestones of recent formation, part of which takes the form of at least one of the mono-, di- and tri-calcium phosphates resulting from the action of phosphoric acid on the limestones, the product containing a maximum of 20% phosphorus by weight. The manufacturing process involves reacting phosphoric acid with the limestones in the presence of water, at least part of which is sea water, to form the phosphate around the shell core, and extracting under reduced pressure the noxious gaseous products resulting from this reaction.
