Seema Minerals & Metals is a leading manufacturer and supplier of the best range of Reactive Silica in India. Reactive Silica offered by us is highly suitable for defluorination in Phosphoric Acid Plants when Silica content in rock phosphate is low and cannot react with fluorine. Active Silica/reactive Silica for phosphoric acid plant is silica which reacts with hydrofluoric acid. Reactive Silica is only used in phosphoric acid manufacturing plant when then reactive silica content is less in Rock Phosphate. When Rock phosphate reacts with Sulphuric Acid fluorine is evolved, reactive silica reacts with fluorine and Fluosilicic acid is formed which gets deposited in fuming chamber which is scraped and cleaned. When reactive silica content is less in rock phosphate fluorine is left free which corrugates the plant. To protect plant Reactive Silica is added externally in rock phosphate according to percentage require
