How Does Rutile Fit into the Titanium Supply Chain?

Understanding Natural Rutile's Value

Natural rutile represents the purest form of titanium dioxide (TiO₂) found in nature, typically containing 93-96% TiO₂. This high purity makes it particularly valuable for manufacturing premium titanium metal products compared to other titanium feedstocks.

While synthetic rutile and titanium slag can also serve as feedstocks for titanium production, natural rutile's inherent purity translates to fewer processing steps, reduced energy consumption, and ultimately, higher-quality end products. This is particularly crucial for applications where material integrity cannot be compromised.

Applications in High-Specification Industries

Rutile from projects like Kasiya serves as a critical raw material for:

• Aerospace components requiring exceptional strength-to-weight ratios
• Medical implants demanding biocompatibility and durability
• Industrial applications needing corrosion resistance
• Defense sector equipment requiring specialized performance characteristics

In titanium metal production, high-purity rutile undergoes chlorination in the Kroll process to produce titanium tetrachloride (TiCl₄), which is then reduced with magnesium to create titanium sponge—the precursor to titanium metal. The initial quality of the rutile directly impacts the performance characteristics of the final titanium products.

What Makes Kasiya's Rutile Strategically Important?

Supply Chain Significance

The validation of Kasiya's rutile by Toho positions the project as a potential cornerstone supplier to critical industries. This is particularly important given:

• Growing concerns about supply chain security for critical minerals
• The strategic importance of titanium in aerospace and defense applications
• Increasing demand for high-purity titanium feedstocks
• Geopolitical pressure to diversify supply sources away from concentrated producers

Recent designations under the EU Critical Raw Materials Act (2023) and U.S. Defense Production Act highlight titanium minerals as strategically important resources, creating additional incentives for development of new supply sources like Kasiya.

Dual-Commodity Advantage

The Kasiya project offers a unique advantage as a dual-commodity operation:

• Primary production of premium natural rutile
• Secondary production of graphite, another critical mineral with applications in batteries and other technologies

This dual-commodity nature provides potential revenue diversification and aligns with the growing demand for battery minerals in the renewable energy transition. Few projects globally offer this combination of critical minerals strategy from a single operation.

Industry Note: While titanium metal accounts for only about 10% of total titanium mineral consumption, it represents the highest-value application with the most stringent quality requirements. The remaining 90% is used primarily in titanium dioxide pigment production.
