Procedure for obtaining a Fertilizer based K zeolu00cdtica using as a source of Potassium the residual Brine of salt industry, Marine

摘要

This work belongs to the branch of Chemistry, specifically the production of Potassium Enriched zeolites for application as Fertilizer in Agriculture. The essence of the invention consists of grinding and sifting the Zeolite to a particle size between 0.5 and 2.0 mm and moreover the Brine Evaporated until the content of potassium chloride in the liquor is from 4 to 9%.Then contact the solid and Liquor for a time between 48 and 120 hours in a relationship between 1 and 3 times of the proportion between the amount of Potassium in the liquor and the cation Exchange capacity of Zeolite used.The Solid was then washed with water until the concentration of CHLORIDES and sulphates in the Water Wash, do not exceed the water used. Finally Air Dried.
