Prepared for Potassium Sulfate of the Orthogonal Test in K-Feldspar-Phosphogypsum-Coke System

Abstract:

The four factors such as alcium silicon proportion, coke dosage, burned time and the addition of solubilizer are studied in poorer oxidative atmosphere at 1200 °C. The grade-analysis and visual preferred plan of orthogonal table are reappeared.The results show the indexs of visual preferred plan of orthogonal table are perfecter,therefore,the plan is used as preferred plan.The product is separated and characterized by infrared.The infrared map shows the product is potassium sulfate . The XRD inflection of samples is studied, waste residue is also effective ingredient besides potassium slufate.It is used again to avoid secondary pollution.
