钒是一种稀有金属,它在发展我国工业尤其是尖端技术中具有极其巨大的意义。在炼制优质结构钢、工具钢以及其他各种特殊钢中,它是一种必不可少的、重要的合金元素。在原子能工业中,钒用来代替价格高昂,产量有限的钽和铌。此外,在化学工业方面,钒的氧化物是一种活性大,用途广的催化剂。大跃进以来,全国工农业出现了空前蓬勃的发展,钒的生产必须以更快的速度增加产量提高质量,才能满足各方面首先是尖端技术方面的迫切需要。我国目前采用的火法冶金提钒(也是世界上最通行的方法),是将含钒矿石经高炉冶炼成含钒生铁,然后用转炉吹炼,钒进入渣中,成为含钒炉渣。最后用化学方法处理而获得钒。这个方法,虽可使铁矿中少量的钒富集到渣中,以便用化学方法提钒,但是工艺过程繁杂,钒的回收率低,一般仅50％左右。这种情况,促使了我们寻求新的更为经济更为有效的提钒方法的研究。
Vanadium is a rare metal that is of tremendous significance in the development of our industry, especially in cutting-edge technology. It is an essential and important alloying element in refining high-quality structural steels, tool steels and various other special steels. In the nuclear industry, vanadium is used to replace expensive tantalum and niobium in limited production. In addition, in the chemical industry, vanadium oxide is a large activity, wide range of catalysts. Since the Great Leap Forward, there has been an unprecedented boom in the country’s industry and agriculture. The production of vanadium must increase its output faster and increase its quality so as to meet the urgent needs of all sectors, above all from the cutting-edge technologies. At present, pyrometallurgy in our country is also the most common method in the world. The vanadium ore is smelted into the vanadium-containing pig iron by a blast furnace, then the converter is used to blow the vanadium into the slag to become the vanadium-containing slag. Finally, chemical treatment to obtain vanadium. This method, although a small amount of vanadium can be enriched in the iron ore slag to chemical methods to mention vanadium, but the process complicated, low recovery of vanadium, usually only about 50%. This situation has prompted us to seek new and more economical and effective methods of vanadium research.
