Beneficiation of Iraqi Akash at Phosphate Ore Using Upgrading Phosphate Ores with Rotary Kilns
electric furnace or in a rotary kiln Since phosphoric acid produced through dry routes contains less impurities its application lies mainly in the high added value areas such as detergents and food additives while phosphoric acid from wet processes is mainly further processed into fertilizersThe semi solid rock then consolidates and hardens as it is discharged from the kiln How Phosphate Rotary Kilns Work Rotary kilns sometimes called calciners are an advanced thermal processing device used for high temperature processing typically with the intention of causing a physical change or chemical reaction within the material
