The present invention relates to a cleaning method of a tantalum and niobium ore conversion, the method comprising molten KOH sub tantalum and niobium ore decomposition, the decomposition product was separated diluted lye and high concentration KOH containing tantalum (niobium) Potassium solid phase by hot water leaching isolated six tantalum (niobium) and a solution containing potassium bias insoluble tantalum (niobium) potassium iron manganese slag precipitate. The hexahydrate (铌) potassium solution is crystallized by alkali to obtain potassium hexahydrate (potassium) acid crystal and crystallization mother liquor, and the crystallization mother liquor returns to the sub-melting salt decomposition step, and the potassium bismuth (potassium) hydride and the iron-manganese slag are decomposed and precipitated by HCl. Potassium (铌) potassium crystallization. Compared with the existing high-concentration and high-toxicity HF acid (>60%) decomposition method, the method can reduce the pollution of F↑[-] from the source and increase the decomposition rate of the hardly decomposed antimony ore by more than 15%. Close to 100% of the ore decomposition rate, with good economic and environmental benefits, and can produce potassium bismuth (potassium), as an intermediate in the preparation of a series of bismuth, antimony products.
