The processes of smelting high vanadium ferrovanadium with vanadium pentoxide and vanadium trioxide are probed into, appropriate parameters are pointed out, and the two processes of smelting high vanadium ferrovanadium are compared.

对使用五氧化二钒和三氧化二钒混合料冶炼高钒铁的工艺进行了探讨，指出了适宜的工艺参数，并对生产高钒铁的两种工艺技术进行了比较。

We adopted a comparatively perfect technics, such as calcineing ore with Calcium, soaking through NH_4HCO_3, enriching the vanadium with 717 anion exchange resin and depositing vanadium with NH_4C1, to recover the vanadium from argillaceous vanadium ore. At this rate, those problems that high content of SiO_2 in the ore, agglomeration in calcination, low transformation rate of dissoluble vanadium and unavailable enrichment of mill run, can be raveled out.

针对粘土钒矿中SiO_2含量太高，焙烧时易结块，可溶性钒转化率低以及不能选矿富集等问题，本课题采用钙化焙烧法焙烧，碳酸氢铵浸出，717~#强碱性阴离子交换树脂富集，以及氯化铵沉钒等方法，提钒效果较为理想。
