Fluorosilicic Acid Production by Byproduct in Wet Method of Phosphoric Acid Production

This report entails the detailed cost evaluation of fluorosilicic acid production as a byproduct from the wet method of phosphoric acid production. The reaction begins with the wet method for phosphoric acid production. Initially, phosphorous rock is treated with sulfuric acid to generate phosphoric acid. This method also results in the production of off gases, including hydrogen fluoride (HF) and silicon tetrafluoride (SiF4), are also released as byproducts. The offgas produced by the wet method are further captured, processed, and filtered to obtain fluorosilicic acid at a desired concentration as the end product.
