| Abstract: | The principle of chemical reaction, process and product indexes in production of WPA integrated with gypsum whiskers from hydrochloric acid and phosphate rock are introduced. The process changes the by-product in WPA production from phosphogypsum to the new materials gypsum whiskers with high value-added, which results in not only decreasing the cost of WPA production but also reducing environmental pollution caused from by-product phosphogypsum emissions. |
