PHOSPHATE FERTILIZER WITH SULFUR AND TRACE ELEMENTS FOR ITS AGRICULTURAL AND INDUSTRIAL USE AND PROCEDURE FOR ITS PREPARATION.

摘要

PHOSPHATE FERTILIZER WITH SULFUR AND TRACE ELEMENTS FOR ITS AGRICULTURAL AND INDUSTRIAL USE AND PROCEDURE FOR ITS PREPARATION. THE FERTILIZER IS OBTAINED BY MIXING BY-PRODUCTS FROM THE MANUFACTURE OF TITANIUM BIOXIDE, VIA SULFATE, RESULTING FROM THE ATTACK ON ILMENITE WITH SULFURIC ACID, IN A BY-PRODUCT RATIO: PHOSPHORITE OF 60-85: 40-15 (P: THE FERTILIZER CONTAINS 5-12% TOTAL P2O5, 3-10% CA, 25-40% SO3 [SULPHATES], 10-17% FE (II), 2-5% FE (III), 0, MN 5-2, 0.02-0.1% ZN AND 3-5% MOISTURE. THESE FERTILIZERS ARE USEFUL FOR CONTRIBUTING PHOSPHORUS, PREVENTING AND CONTROLLING IRON CHLOROSIS AND AS A RAW MATERIAL TO MANUFACTURE OTHER COMPLEX FERTILIZERS.
