Clean TeQ Wins Major Rio Tinto Rincon Lithium Contract

Understanding the Rincon Lithium Project's Strategic Importance

Nestled within Argentina's renowned Lithium Triangle, the Clean TeQ Rio Tinto Rincon lithium project represents a cornerstone of Rio Tinto's expansion into battery minerals. This ambitious development, operated through wholly-owned subsidiary Rincon Mining, targets production of up to 60,000 tonnes of lithium carbonate equivalent annually by 2028.

The project's strategic positioning cannot be overstated. Furthermore, argentina lithium brine insights demonstrate that Argentina contributes approximately 17% of global lithium production, ranking as the world's second-largest producer behind Australia. The U.S. Geological Survey's 2024 Mineral Commodity Summaries highlight that South America collectively accounts for roughly 51% of worldwide lithium output, with the Lithium Triangle containing an estimated 58% of global reserves.

Key Project Specifications:

• Location: Salta Province, Argentina
• Annual Capacity: 53,000-60,000 tonnes LCE
• Project Lifespan: 40+ years
• Operator: Rincon Mining (Rio Tinto subsidiary)

The timing proves critical as global lithium demand accelerates. According to the International Energy Agency's Global EV Outlook 2024, lithium requirements are projected to surge dramatically through 2030 as electric vehicle adoption intensifies worldwide. In addition, insights from global lithium podcast insights highlight the complex market dynamics shaping this growth trajectory.

Why Did Rio Tinto Select Clean TeQ's MBIX Technology?

Rio Tinto's technology selection process culminated in awarding Clean TeQ Water a US$12.5 million contract for their proprietary CLEAN-IX Moving Bed Ion Exchange technology. This decision reflects growing industry recognition of advanced processing solutions that address both operational efficiency and environmental sustainability.

According to Clean TeQ CEO Peter Voigt, as reported in Mining Weekly on November 6, 2025, the MBIX system delivers dual benefits by reducing lithium losses during processing while simultaneously decreasing freshwater consumption. This combination proves particularly valuable in Argentina's water-stressed lithium production regions.

Technical Advantages of MBIX:

• Continuous Operation: Unlike traditional fixed-bed systems, MBIX enables uninterrupted processing
• Enhanced Recovery: Minimises lithium waste during concentrate softening phases
• Water Efficiency: Reduces freshwater requirements in arid operational environments
• Scalability: Designed for large-scale industrial applications

The technology addresses a critical processing stage where lithium concentrates require softening to remove polyvalent cations like calcium and magnesium. However, these impurities interfere with downstream lithium extraction efficiency, making effective removal essential for optimal production yields.

Ion exchange technology has served industrial applications for over seven decades, but moving bed configurations represent modern advancement over traditional batch-processing methods. Consequently, the continuous nature of MBIX operations potentially reduces downtime and improves overall plant utilisation rates.

Contract Specifications and Delivery Timeline

The November 2025 contract award encompasses comprehensive engineering and supply services valued at A$19.2 million. This represents one of Clean TeQ's largest contracts to date and marks their inaugural major project entry into South America's lithium sector.

The comprehensive package includes complete engineering design services, equipment procurement, and installation support. Furthermore, Clean TeQ will integrate their MBIX system with Rincon's existing infrastructure over the three-year delivery schedule, aligning with large-scale industrial project timelines.

According to Mining Monthly's coverage, this contract represents Clean TeQ's first major South American project, positioning the company strategically within the world's most productive lithium region. The award validates their technology capabilities on an international scale with a tier-one mining operator.

Strategic Benefits for Both Organisations

Clean TeQ's Market Positioning

This partnership delivers multiple strategic advantages for Clean TeQ Water. The contract provides crucial revenue diversification while establishing credible market presence in the Lithium Triangle. As CEO Peter Voigt noted, the award serves as strong endorsement of MBIX as a best-in-class solution for lithium refining applications.

The validation from Rio Tinto, a globally recognised mining leader, significantly enhances Clean TeQ's competitive positioning. This credibility boost could unlock additional opportunities across South America's expanding lithium development pipeline.

Clean TeQ Strategic Gains:

• Geographic Expansion: Entry into South America's dominant lithium region
• Technology Validation: Tier-one miner endorsement strengthens market credibility
• Revenue Scale: One of company's largest contracts provides substantial cash flow
• Market Positioning: Establishes presence for future regional opportunities

Rio Tinto's Operational Advantages

For Rio Tinto, adopting MBIX technology aligns with broader operational efficiency and sustainability objectives. The technology's claimed benefits of reduced lithium losses and decreased freshwater consumption directly support both cost optimisation and environmental stewardship goals.

Water scarcity represents a persistent challenge across Argentina's lithium-producing regions. Consequently, the Atacama Desert and surrounding areas experience chronic water stress, making efficient processing technologies strategically important for long-term operational sustainability.

Industry Implications and Technology Adoption Trends

Clean TeQ's contract win signals growing industry acceptance of advanced ion exchange solutions in lithium processing. This trend reflects the sector's increasing focus on operational efficiency amid rising global demand projections.

The lithium industry has historically relied on three primary processing approaches: traditional brine evaporation, hard rock mineral processing, and emerging direct lithium extraction boost technologies. Advanced ion exchange systems like MBIX represent evolution toward more efficient, less resource-intensive methods.

Market Development Indicators:

• Technology Maturation: Ion exchange applications expanding beyond traditional water treatment
• Sustainability Focus: Environmental considerations driving technology selection
• Efficiency Demands: Rising lithium prices incentivising loss reduction technologies
• Scale Requirements: Large producers seeking proven technologies for industrial-scale operations

Voigt's statement about seeing "significant global opportunity for MBIX as a critical enabler of cost-effective, sustainable lithium production" reflects broader industry confidence in advanced processing solutions as demand accelerates over coming decades.

What Role Does Argentina Play in Global Lithium Strategy?

The Clean TeQ Rio Tinto Rincon lithium project exemplifies Argentina's strategic approach to lithium resource development. Government support through frameworks like the Régimen de Incentivo a las Grandes Inversiones (RIGI) demonstrates national commitment to attracting foreign investment in the sector.

Argentina's lithium strategy emphasises leveraging the country's substantial reserve base while encouraging technology transfer and local capacity building. Projects like Rincon create employment opportunities while generating export revenues and supporting regional economic development.

National Strategic Benefits:

• Export Revenue Generation: High-value lithium carbonate exports
