| Abstract: | The theory and process flow for comprehensive utilization of by-product fluosilicic acid from phosphate fertilizer plant with ammonium bicarbonate method are discussed. A variety of fluorides can be produced with this process, such as ammonium fluoride, sodium fluoride,aluminum fluoride,cryolite,etc. ,also with by-products carbon white and ammonium chloride. In particular,the article introduces the experiment to produce cryolite with fluosilicic acid,lists the experimental results and forecasts the prospect for industrial production. |
