Regenerative Chloride Lead (“RCL”) Technologies

Overview

Temas’ portfolio of patents focuses on hydrometallurgical extraction from concentrates, whole ores, slags, and tailings, significantly enhancing recovery of critical metals, battery metals, PGMs, precious and base metals, and REEs. The patented RCL process achieves materially higher through-yields and substantially lower capital and operating costs compared to traditional methods, ideally suited for treating increasingly complex ores.

Validated Cost Reduction

The ORF platform’s efficiency—validated with over 65% cost reduction in TiO₂ processing—is expected to deliver similar economic gains for Nickel and other complex ores.

Environmental Performance

The RCL platform’s closed-loop design and >95% reagent recycling deliver ESG and environmental benefits across Nickel, Gold, REEs, and beyond—not just TiO₂.

High Recovery Potential

With 99.8% TiO₂ purity proven in pilot testing, the RCL platform is built to maximize recovery, purity, and margins across all target metals.

Key Advantages

  • Direct removal of many target elements as valuable high purity metals, battery salts or metal sulfides.
  • It monetizes traditionally deleterious Mg and excess Fe as pure commercial grade value added products.
  • Regenerates reagents (mainly HCl acid and MgCl) in a closed reaction loop that maximizes reaction kinetics and product through-yields.
  • Simplified process flow and energy efficiency results in a 30-65% reduction in CAPEX and OPEX resulting in superior operating margins with far less negative environmental impact.

Comparison of ORF-RCL Process for Titanium Production

Cost and Energy Efficiency

A University of Minnesota study on ORF Technologies’ patents concluded that the TiO₂ recovery process could slash production costs by ~ 50-60%, and the process is also less energy-intensive compared to the industry standard.

Market Potential

The global market for TiO₂, valued at US$21.23 billion, is anticipated to grow at a compound annual growth rate of 6.2% through 2032, signifying a substantial opportunity for ORF Technologies’ efficient recovery process.

Quality and Versatility

ORF Technologies’ patented process can produce high-quality Titanium Dioxide (TiO₂) from low-grade materials and is applicable to all ilmenite ores, including those rich in Chromium (Cr), Cobalt (Co), and Vanadium (V), thus enabling the extraction of additional value from elements that are typically not recoverable with other methods.

RCL MULTI-METAL Strategic Advantage

Diversification

This multi-mineral capability allows Temas to diversify beyond a single commodity, opening up revenue streams from Nickel, precious and platinum group metals, REEs or other critical minerals as market conditions and strategic opportunities dictate.

Flexibility in who we are available to partner with further diversifies potential revenue streams leveraged from the IP while effectively managing the risks.

Enhanced Project Economics

For polymetallic deposits, RCL offers the potential to extract multiple valuable metals from a single feedstock, significantly enhancing project economics.

Broader Licensing Appeal

As a licensable technology, RCLs proven adaptability to various minerals, including those listed in our IP like Nickel, dramatically widens its market appeal to miners globally who are looking for innovative solutions for their specific resources. 

Temas is actively pursuing global licensing opportunities, with third-party companies currently evaluating Temas IP for potential operations in Indonesia, Australia, and North America.
