ASX-listed Clean TeQ Water has been awarded a $12.5-million (A$19.2-million) contract by Rincon Mining, a wholly owned subsidiary of Rio Tinto, for the Rincon lithium project in Argentina’s Salta province.

The contract, one of the largest in Clean TeQ’s history, covers the engineering design, procurement and supply of a lithium concentrate softening plant that will use the company’s proprietary CLEAN-IX Moving Bed Ion Exchange (MBIX) technology.

The award represents Clean TeQ's first major project in South America and reinforces its position as a global player in lithium refining and direct lithium extraction (DLE). Delivery will take place over a three-year schedule, aligned with large-scale industrial installation timelines.

Clean TeQ CEO Peter Voigt said the award validated the company’s technology and capabilities. “This contract is one of our largest and is our first in the South American lithium triangle. The award is a strong endorsement of our MBIX technology as a best-in-class solution for, in this case, lithium refining – where it reduces lithium loss and fresh water use. As lithium demand accelerates over the coming decades, we see a significant global opportunity for MBIX as a critical enabler of cost-effective, sustainable lithium production.”
