Refining & Grade Specs

Vanadium Refining Methods and Grade Specifications

The transformation of Vanadium concentrate into refined products suitable for industrial use requires specialized metallurgical and chemical processes. Vanadium is refined into 4 primary commercial forms, each serving specific end-use sectors.

Refining Processes

The primary refining and processing pathways for Vanadium include:

1. Salt roasting of steel slag
2. Solvent extraction
3. Fusion and leaching

Product Forms and Grade Specifications

Refined Vanadium is available in the following commercial forms, each with specific purity requirements:

Quality Standards and Benchmarks

International standards for Vanadium products are established by organizations such as ASTM International and various national standards bodies. Pricing is referenced against Fastmarkets/Metal Bulletin assessments. These standards define minimum purity levels, acceptable impurity limits, and testing methodologies that facilitate international trade.

Refining Capacity and Geography

Global refining capacity for Vanadium is concentrated in a limited number of countries. China controls approximately 55% of primary production and plays a significant role in downstream refining. Efforts to diversify refining capacity are a key priority for governments seeking to reduce supply chain dependencies, particularly in the high-strength steel alloys sector.
