Process for the preparation of micronutrient blends.

摘要

Metal complexes having high bulk density and a process for the production of the same without the generation of heavy metal-contaminated effluents are disclosed. Solid complexes of EDTANaFe and EDTAKFe having high bulk densities are formed by reaction with mixed metal solutions containing low chromium levels, followed by total drying of the resulting mixture in the same processing equipment without the prior separation of the sulfate salts formed. The amounts of the various metals in any given formulation can be preselected.
