Fosfatos de Lizardo, Edo. Falcón: Parte II: Fosfatos de aluminio. Estudios de solubilización y obtención de H3PO4

Abstract

Lizardo`s ores have been considered to replace Riecito`s ones as a source of phosphorites for fertilizer industry. A big interest for the Degree Thesis resumed in the present work (1)(2), so as for the preview (3) has been produced In this article are presented and discussed the pure aluminium phosphates solubilities studies with and with-out previews thermal treatment. Also is done on the simples superphosphates obtained with sulfuric acid attack Finally the results of the H3PO4 humid recovery process and his purification are given.
