Key Players
Competitive Landscape
Competition in non-cyanide gold leaching reagents runs through four business models with different routes to mine qualification. The field includes proprietary glycine platforms and licensed thiosulfate systems as well as tailings-processing technologies and modular alternative-leaching developers. Mine operators compare ore-specific recovery with downstream recovery requirements before licensing chemistry or committing to a pilot.
Industrial-scale proof became a stronger competitive threshold in June 2026 when NVRO Metals Limited announced the proposed NVRO Metals Hub acquisition. The site places the NVRO Process beside existing hydrometallurgical infrastructure for larger customer-feed campaigns. Draslovka reported in June 2025 that twelve GLT pilots were testing directly at customer sites as its licensing pipeline expanded. Mine operators now compare longer operating evidence and local engineering support before committing to a larger campaign.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| August 2026: NVRO Metals Limited completed a 202-hour continuous production demonstration on Hecla Greens Creek material and reduced solids mass by about 70% during the leaching campaign. | Mine operators need continuous customer-feed evidence before an alternative flowsheet can justify industrial engineering work. | Process developers are extending batch testwork into longer campaigns that use named customer material under continuous operating conditions. | Successful campaigns can support engineering studies and larger processing commitments for refractory tailings or sulfide feed. |
| February 2026: Draslovka a.s. partnered with Avathon to commercialize a combined mining-control offering using MetOptima and Blue Cube technologies. | Variable ore and slurry conditions require faster operating feedback before plants change reagent dosage or recovery settings. | Reagent companies are pairing leach chemistry with live mineral sensing and metallurgical control tools for operating mines. | Integrated control tools can deepen technical support for GLT qualification and reduce adjustment time during site campaigns. |
| July 2026: NVRO Metals Limited signed a non-binding MOU with Hecla for a proposed 35,000-metric-ton campaign at the NVRO Metals Hub. | Mine owners need larger feed campaigns before they commit engineering resources to a new tailings recovery route. | Customer validation is moving from laboratory samples toward multi-thousand-ton campaigns tied to dedicated processing infrastructure. | A successful campaign can lead to toll-processing or licensing revenue if recovery and residue economics remain acceptable. |
Clean Mining Pty Ltd commercializes thiosulfate processing services for gold operations that need a non-cyanide leach route. Cycladex Ltd develops alternative-to-cyanide pilot routes for difficult and refractory gold feed at mines.

The four companies cover proprietary reagent chemistry and licensed thiosulfate processing alongside tailings treatment and refractory-ore pilot programs.
Who leads the non-cyanide gold leaching reagents market?
Draslovka a.s. discloses customer-site GLT testing and licensing activity that places its chemistry in commercial mine programs. Public company disclosures do not provide a comparable revenue-share measure for all four companies, so no numerical leadership ranking is stated.
Which suppliers have documented qualification or quality approvals?
Draslovka a.s. documents customer-site GLT testing and NVRO Metals Limited publishes continuous customer-feed demonstration results. Caledonia Mining's SEC filing records Cycladex pilot work at Blanket Mine under an alternative-to-cyanide process.
Which companies provide mine-trial and alternative-leaching products?
Draslovka a.s. supplies glycine-based leaching technology and Clean Mining Pty Ltd commercializes a thiosulfate processing route. Cycladex Ltd develops alternative-to-cyanide recovery for refractory feed and NVRO Metals Limited focuses on tailings and complex sulfide feedstocks.
Which suppliers serve Australia and North America?
NVRO Metals Limited is developing processing infrastructure in Australia and works with North American customer material from Hecla. Draslovka a.s. supports international mine programs through GLT testing and licensing backed by site engineering support. Clean Mining Pty Ltd serves gold miners globally through thiosulfate technology developed in Australia with CSIRO. Cycladex Ltd is a United Kingdom company conducting alternative-to-cyanide pilot work at mining sites abroad.
Representative Company Overview
| Company | Positioning | Verified Development |
|---|---|---|
| Draslovka a.s. | Commercial glycine-leaching platform with customer-site GLT testing and international mine-market outreach. | In September 2025, Draslovka presented Glycine Leaching Technology to Indonesian mining operators during an official Czech mining-technology mission. |
| NVRO Metals Limited | Tailings and complex-sulfide recovery developer moving the NVRO Process from customer validation toward infrastructure-backed industrial deployment. | In June 2026, NVRO Metals Limited announced a 77.6-million-tonne independent resource estimate at the NVRO Metals Hub to support future NVRO Process deployment. |
| Clean Mining Pty Ltd | Australian thiosulfate commercialization company providing non-toxic ore-processing services and a licensed cyanide-free gold recovery route. | In September 2026, Clean Mining's official website disclosed a management change and planned relaunch of Non-Toxic Ore Processing Services built around thiosulfate technology. |
| Cycladex Ltd | United Kingdom alternative-to-cyanide recovery developer serving refractory ore, tailings, and modular pilot applications. | In September 2026, Cycladex's official website documented an active South African pilot plant with 21 experiments completed and 85% peak gold recovery. |
Research Methodology
The companies mapped here illustrate market structure rather than an exhaustive revenue or technology ranking. Inclusion requires current verifiable evidence that a company supplies alternative gold-leaching reagents or a licensed non-cyanide recovery process within the defined scope. Evidence comes from regulator records and official company announcements as well as third-party certifications and public filings. Capabilities are attributed to the stated GLT or thiosulfate route and to the Cycladex or NVRO process family rather than generalized across broader corporate portfolios. Market-share estimates remain proprietary FMI assessments for the 2026-2036 forecast period and are not public company disclosures.
