RZOLV Reports 99.9% Silver Extraction from Solar-Panel Concentrate in Bench-Scale Testing

What happened

RZOLV Technologies reported 99.9% silver extraction to solution from solar-panel concentrate in bench-scale testing, based on independent ALS assays of the feed and final washed residue. Electrowinning tests showed 40.4% silver recovery within 10 minutes, rising to 99.85% after five hours.

Confirmed

Global impact / market context

Higher silver extraction means more of the valuable metal can be sold from each end-of-life solar panel, which could improve recycling economics. Cheaper non-cyanide processing may also lower costs and regulatory hurdles, making solar-panel recycling more attractive to manufacturers and recyclers.

Analyst inference

The results remain bench-scale, meaning small laboratory tests rather than commercial production. Investors would need larger pilot runs and independent verification before treating the process as commercially proven, and the company said it is in talks with manufacturers, recyclers, technology providers and refiners.

Analyst inference

What to watch

1. Watch whether RZOLV moves the 99.9% silver extraction result from bench-scale testing into larger pilot or commercial-scale trials, since small tests can behave differently at industrial volumes and with varied panel feed material. Confirmed
2. The company aims to build a global circular supply chain that recovers silver from end-of-life solar panels and returns it to manufacturing, so progress on agreements with manufacturers, recyclers, technology providers and refiners is a key signal. Proposed
3. Track the economics of the non-cyanide process, including reagent costs and silver selling prices, because strong extraction rates only create value if the recovered silver can be sold at a profit after processing costs. Analyst inference
