PROCEDURE FOR CONTROLLING THE GRANULATION OF LEAD PRODUCED IN TROMELS BY CEMENTATION WITH METAL ZINC FROM ITS AQUEOUS SOLUTIONS. HYDROMETALLURGICAL PROCEDURE FOR THE CONTROL OF THE GRANULOMETRY OF LEAD FROM AQUEOUS DISSOLUTIONS, REDUCED TO METAL IN TOMMELS OR ROTATING DRUMS OF CEMENTATION WITH ZINC, ALLOWING SO FAR TO OPERATE THE OPERATION OF THE OWN OPERATION OF THE OWN , DRYING, MELTING ... THE SELECTION OF THE CEMENT GRANULOMETRY IS ACHIEVED THROUGH THE ADJUSTMENT OF THE FERRIC / FERROUS ION PROPORTION OF THE DISSOLUTIONS THAT CONTAIN IT THROUGH THE QUANTIFIED DOSAGE OF REDUCING CHEMICAL REAGENTS. IT HAS APPLICATION IN THE HYDROMETALLURGICAL INDUSTRY FOR LEAD PRODUCTION, IN ITS SOLID RECOVERY OR SOLUTIONS FROM PRIMARY OR SECONDARY SOURCES, AND / OR IN ITS REMOVAL FOR ENVIRONMENTAL REASONS OR AS PURIFICATION IN OTHER PRODUCTIVE PROCESSES.
