A process for recovering useful products from the residual dust from a cement kiln to produce cement clinker

THE INVENTION CONCERNS A PROCESS USEFUL PRODUCTS RECOVERY FROM DUST REFIDUELLE OVEN CEMENT. DUST is collected and COMMENCED IN ARC FURNACE IT IS RENDERED. TEMPERATURE SOUGHT FOR MELTING DUST IS ENOUGH FOR THE HIGH ALKALINE SULPHATES PRESENT IN DUST ARE ELIMINATED BY VOLATILIZATION SO NOT LEAVE THAT COMPOSITION ACCEPTABLE FOR PRO REDUCTION OF CEMENT CLINKER. SUBSTANCES ARE COLLECTED volatilized TO CONSTITUTE A SECOND PRODUCT USEFUL FOR EXAMPLE MATERIAL RICH IN POTASSIUM SUITABLE FOR PRODUCTION OF CHEMICAL CONTAINING POTASSIUM, SUCH AS FERTILIZER. SCOPE: PRODUCTS USEFUL FOR RECOVERY FROM DUST RESIDUAL CEMENT OVENS .
