一九八七年一月二十日至二十一日由湖南省冶金厅主持,在衡阳市召开五氧化二钒车间改造工程初步设计审查会。该车间曾于七十年代建在衡阳市锰制品厂,原设计规模为年产五氧化二钒80～100吨,后因各种原因停建。现改造规模扩大到年产五氧化二钒1000吨,采用钒渣作原料。改造后的主要工艺过程是:原料钒渣经破碎、球磨、磁选后配入苏打、芒硝、食盐等进行混合;混合料经焙烧、球磨浸出、沉淀、过滤;滤饼再经脱水、熔化.铸成片状
From January 20 to January 21, 1987, chaired by the Metallurgical Department of Hunan Province, a preliminary design review meeting of the vanadium pentoxide workshop renovation project was held in Hengyang. The workshop was built in the seventies in Hengyang City, manganese products factory, the original design scale of annual output of vanadium pentoxide 80 to 100 tons, after the suspension due to various reasons. Now the scale of reform expanded to an annual output of vanadium oxide 1,000 tons, the use of vanadium slag as raw material. After the transformation of the main process is: the raw material vanadium slag by crushing, ball milling, magnetic separation after the allocation of soda, thenardite, salt and other mixed; mixture roasting, ball mill leaching, precipitation, filtration; filter cake then dehydration, melting.
