HIGH-QUALITY STANDARDS FOR VANADIUM CHLORIDES

The
production of the Stratcor® high-purity
vanadium oxides takes place at Strategic Minerals'
Hot Springs, Arkansas plant. Starting with whichever
cost-effective feedstocks are available - ores,
residues, ashes, or spent catalysts - the plant
uses four production operations to remove impurities
and contaminants, as shown in the following diagram about vanadium oxide production:
Producing
High-Purity Vanadium Oxide at ISO-9001:2000
Facilities in Hot Springs, Arkansas
The
process starts when the raw materials are leached
to form a water-soluble vanadium compound and unwanted
solids are removed. The solution is then fed into
a liquid-liquid ion-exchange circuit where vanadium
is separated from other metallic impurities.
The
resulting high-purity vanadium liquor is further purified
in a growth-type crystallizer. The process slowly
grows large ammonium-metavanadate crystals, minimizing
surface impurities as well as crystal inclusions.
For customers ordering ammonium
metavanadate, the product is now ready to be dried
and shipped.
Final
purification of vanadium
pentoxide takes place in a calciner that drives
off ammonia and any low-melting-point contaminants
still present. Only the highest-purity vanadium pentoxide
is sold to chemical customers or used at Hot Springs in vanadium-chloride
production.
