一种通过将钒渣进行钠化球团焙烧来实施提钒的方法
摘要：
本发明属于提钒化工技术领域，公开了一种通过将钒渣进行钠化球团焙烧来实施提钒的方法，该方法包括以下步骤：(1)将钒渣与钠化添加剂混合；(2)将粘结剂的水溶液喷洒在经步骤(1)混合后的混合料的表面上且制备成球团；以及(3)将所述球团焙烧后破碎，再将破碎后的球团溶解在水中浸出。本发明通过将钒渣进行钠化球团焙烧来实施提钒的方法，大大提高了钒的浸出率，同时也避免了钒渣在高温焙烧过程中产生的粘结现象，以及在本发明的钠化球团焙烧的方法中，不需要添加提钒后的残渣，因此，本发明的渣钠化球团焙烧的方法工艺简单易用、适应范围广、成本低，具有很高的社会效益和经济效益。
摘要（英）：

The invention belongs to the field of vanadium extraction chemical technologies, and discloses a method for implementing vanadium extraction through carrying out Na-modification pellet roasting on vanadium slags. The method comprises the following steps: (1) mixing vanadium slags with a Na-modification additive; (2) spraying an aqueous solution of a binder to the surface of a mixture obtained in the step (1), and preparing the obtained object into a pellet; and (3) roasting the pellet, crushing the pellet, dissolving the crushed pellet in water, and leaching the obtained product. According to the method for implementing vanadium extraction through carrying out Na-modification pellet roasting on vanadium slags disclosed by the invention, the leaching rate of vanadium is greatly improved, and a phenomenon that vanadium slags are bonded in the process of high-temperature roasting is also avoided; and in a Na-modification pellet roasting method in the invention, residues produced after vanadium is extracted are not required to be added, therefore, the Na-modification pellet roasting method is simple in process and easy to use, wide in application range and low in cost, and has extremely high social and economic benefits.
