本文研究了含钒钠化渣的“风化”处理对浸取过程的影响以及采用碳酸化法从浸取液中回收碳酸钠的可能性。结果指出:含钒钠化渣经“风化”处理后完全消除了负二价硫对回收钒的影响,有利于钒,钠的浸取和固液分离。整个工艺过程中不耗氧化剂,不须溶液蒸发浓缩,生产费用低。采用本工艺可一次回收90～92％的钒和55～56％的钠。 This paper studies the effect of “weathering” treatment of vanadium-bearing sodium slag on the leaching process and the possibility of recovering sodium carbonate from the leachate by carbonation. The results show that the vanadium-bearing sodium slag after “weathering” completely eliminates the negative effect of negative divalent sulfur on the recovery of vanadium, which facilitates the leaching of vanadium and sodium and the solid-liquid separation. The entire process does not consume oxidants, without evaporation of the solution concentration, low production costs. The process can recover 90-92% vanadium and 55-56% sodium once.
