Vanadium bearing oil based fuels are burnt in the boilers of electric power generating plant and vanadium is left in the fly ash and boiler slags. Vanadium in these ashes and slags is recovered by the same process as for vanadium coming from Flexicoke.
Processing of vanadium: a review - ScienceDirect
The supply and demand of vanadium products during the past 20 years has been relatively stable and subject to a gradual decline in delivered price. The stone describes established industrial processes for recovery of vanadium from sources such as raw ore and process reverts.
Vanadium Extraction Process - Mineral Processing …
The extraction and recovery process of vanadium as a by-product from the tailings of a uranium processing plant poses many problems. In this study vanadium is recovered from impounded resin-in-pulp tailings and from the current tailings of a uranium plant which did not include a circuit for vanadium recovery in its initial design.
Processing of vanadium: a review - ScienceDirect
A roast-leach process is used in South Africa for the production of vanadium oxides from magnetite ores while some of the slag is converted to ferrovanadium. A portion of the slag is exported to Europe for the production of vanadium oxide. Slag from steel plants using iron sands as feedstock is also exported from New Zealand to recover oxides.

Vanadium Statistics and Information - USGS
Vanadium, when present in small amounts in certain ferrous alloys, can significantly improve their properties. Manufacturers of automobiles and machinery recognized the toughness and fatigue resistance of vanadium alloys as far back as the early 1900s, incorporating the alloys in axles, crankshafts, gears, and other critical components.
Ferroalloy - Wikipedia
Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the ...
