| Abstract: | Effect of various extractive systems (triisoamyl phosphate/HF+H2SO4, n-octanol/HF+H2SO4, n-octanol/HF+HNO3) used to obtain potassium heptafluorotantalate from plumbomicrolite-based raw materials on the purity and characteristics of sodium-reduced tantalum powders was studied. Application of the extractive systems provides production of high-purity potassium heptafluorotantalate from raw materials based on products formed in processing of the plumbomicrolite concentrate. |
