| 摘 要： | 综述了1980-2015年期间钒矿、含钒磷铁、废钒催化剂、钢渣和石煤等常见提钒原料之提钒技术的研究进展,对目前较具代表性的提钒工艺技术进行了较系统地分析总结,将这些提钒工艺技术归结为冶金工艺、焙烧工艺、湿法提钒、其他新型工艺四大类进行分类阐述;对各类提钒工艺技术进行了举例说明,对其基本过程进行了概述,并对其优缺点进行了较客观的分析和评述。在此基础上,发现和指出了长期以来我国提钒工艺过程中普遍存在的主要问题:首先,钒资源提钒的工艺技术水平仍然较低,废弃物较多,环境污染较严重;其次伴生矿或元素利用较低,钒资源综合利用程度较低。最后,指出了提钒技术的发展趋势:在强调环境保护的背景下,乞待开发新的环境污染较少、钒资源综合利用程度较高的提钒工艺。 |

| Abstract: | The progress of vanadium extraction technology for common vanadium extraction raw materials, including Vanadium ore, ferro-phosphorous containing vanadium, waste vanadium catalyst, steel slag, and bone coal and so on, during the period 1980 to 2015 is reviewed.All the current representative technologies of vanadium purification are systematically analyzed and summarized.These extraction technologies are attributed to four categories:metallurgical process, roasting process, wet process and other new process.And they are described respectively.Examples are given for each kind of technology.The basic processes for all kinds of vanadium extraction technology are described.Their advantages and disadvantages are more objective commented.Base on that, main problems during the processes of vanadium extraction technology in our country are discovered and pointed out.First of all, technology levels of vanadium purification from vanadium resources are still low;their wastes are too much;the environmental pollution is very serious.What is more, utilization of associated minerals or elements is too little;the level of comprehensive utilization of vanadium resources is too low.Finally, the development trend of vanadium extraction technology is pointed out:under the background of emphasizing environmental protection, new vanadium purification processes, which are with less environmental pollution and high degree of utilization of vanadium resources, are eager to be developed. |
