Mining the Past: Lithium's New Frontier in Secondary Sources

Why It Matters

Extracting lithium from existing waste reduces environmental impact and diversifies supply, easing pressure on scarce primary deposits as demand soars.

Key Takeaways

• Quiborax to pilot lithium extraction from Chilean tailings
• LieNa tech recovers up to 90% lithium from waste streams
• ANSTO and Lithium Australia co‑developed the processing method
• Secondary lithium could meet 15% of global demand by 2030
• Project aims to cut carbon intensity of lithium production

Pulse Analysis

The lithium boom, driven by electric‑vehicle batteries and grid storage, has pushed producers to explore unconventional sources. While traditional mining expands into remote deserts, secondary recovery taps into the massive volumes of waste already generated by copper and gold operations. This approach not only unlocks a hidden resource but also addresses mounting environmental scrutiny, offering a pathway to lower‑impact lithium production.

At the heart of the Chilean initiative is the LieNa technology, a hydrometallurgical process that leaches lithium from tailings with up to 90% recovery rates. Developed jointly by ANSTO and Lithium Australia, the method uses a proprietary solvent blend that selectively isolates lithium ions while minimizing reagent consumption. GEM Mining Consulting’s involvement ensures rigorous feasibility studies and integration with existing waste‑handling infrastructure, accelerating the timeline from pilot to commercial scale.

If Quiborax’s pilot demonstrates economic viability, the implications could ripple across the global market. Secondary lithium could supply a meaningful share of the projected 15% demand increase by 2030, reducing reliance on new mines that often face permitting delays and community opposition. Moreover, the lower carbon footprint of waste‑based extraction aligns with ESG goals, making the product attractive to battery manufacturers seeking greener supply chains. Investors and policymakers will watch Chile’s experiment closely, as it may set a template for other resource‑rich nations to monetize their mining by‑products while advancing sustainability targets.
