company news about ferro vanadium production

Ferro vanadium is an alloy of iron and vanadium, typically containing between 35% and 80% vanadium, depending on the intended application. Here are the general steps involved in the production of ferro vanadium:

1. Vanadium extraction: The vanadium is typically obtained from vanadium-containing ores, such as vanadinite, patronite, or carnotite, through a variety of extraction methods, including roasting, leaching, and precipitation.

2. Smelting: The extracted vanadium is then mixed with iron in the form of iron oxide or pig iron and melted in a furnace. The temperature is raised to between 1400°C and 1500°C to ensure complete melting.

3. Reduction: After melting, the vanadium and iron mixture is reduced with a carbon source, such as coke or charcoal. This process removes any remaining oxygen and converts the vanadium to a metallic form.

4. Refining: The molten metal is then refined to remove impurities, including slag, sulfur, and other elements. Refining is typically done using an oxygen injection process, which removes impurities while also reducing the carbon content of the mixture.

5. Solidification: Once the refining process is complete, the ferro vanadium is cast into ingots or other shapes and allowed to cool and solidify. The resulting product is then ready for use in various applications.
