概论钒属于高熔点稀有金属。主要用作钢的合金元素添加剂,用途较为广泛。多、快、好、省地冶炼钒铁,钒对发展国民经济具有一定的意义。由于矿石中含钒品位很低,不能直接从矿石得到钒铁。为此,必须将矿石经一系列处理(包括火法和湿法处理),如图1所示,获得工业五氧化二钒。工业五氧化二钒再 Introduction Vanadium is a refractory rare metal. Mainly used as steel alloy additive, more widely used. Ferrovanadium is more, faster, better and more economically conserved. Vanadium is of great significance to the development of the national economy. Due to the very low grade of vanadium in the ore, vanadium iron can not be obtained directly from the ore. To do this, the ore must be subjected to a series of treatments, including fire and wet treatments, as shown in Figure 1, to obtain industrial vanadium pentoxide. Vanadium pentoxide industry again
