本文针对钠化钒渣含钠、磷、硫、硅高的特点,提出了碳酸化—中性铵盐沉钒制取精V_2O_6及回收钠盐的工艺流程,可制得V_2O_5品位大于99%的精钒产品,以碳酸钠形式回收的钠盐纯度高,可返回用作铁水的直接钠化处理。在实验室条件试验的基础上进行了扩大试验,钒收率达92.6%,钠的收率为42.8%。 In view of the high content of sodium, phosphorus, sulfur and silicon in sodium vanadium slag, the paper proposed a process flow of carbonation-neutral ammonium salt vanadium precipitation to recover fine V_2O_6 and recovering sodium salt, and the grade of V_2O_5 was more than 99% The refined vanadium product, sodium salt recovered in the form of sodium carbonate, is highly pure and can be returned for direct sodium treatment of hot metal. Based on the laboratory test, the expansion test was conducted. The vanadium yield was 92.6% and the sodium yield was 42.8%.
