Gold.
Green Mining's flagship case.

Precious metal, store of value, conductor, catalyst. Gold concentrates perennial demand in jewelry, electronics, finance, and medicine. At Green Mining, it's also the commodity where technology shows its most expressive benchmark: ~114 hours cycle reduced to ~16 hours. Historical gold tailings still carry grams per ton that conventional flotation left behind.

Industrial uses

What gold is used for, today.

Demand distributed across four major vectors, with composition varying by economic and geopolitical cycle — but never zeroing any of them.

46% of demand

Jewelry and fine goods

Largest demand block globally. Concentration in India and China. Alloyed with silver, copper and palladium for different karats and tones.

22% of demand

Store of value

Central banks, ETFs, institutional and retail investors. Hedge against inflation, currency devaluation, geopolitical risk. Liquid OTC market in London and Zurich.

7% of demand

Electronics

Connectors, contacts, bonding wires in semiconductors. Irreplaceable where corrosion and contact resistance are critical — smartphones, aerospace, data center servers.

Growing niche

Medicine and biotech

Gold nanoparticles in molecular diagnostics and oncology drug delivery. Implants, dental prosthetics. Neutral immune response.

Specialized industrial

Chemical catalysis

Gold nanocatalysts in chemical synthesis and environmental remediation. Fuel cells. Mature in lab, growing industrial diffusion.

Aerospace

Coatings and thermal reflection

Thin films on satellites, astronaut visors, precision instruments. Superior infrared reflectivity over aluminum at critical frequencies.

Why it's in tailings

The historical loss.

Conventional gold flotation recovers between 60% and 75% of the contained metal. The rest goes to tailings. Over a century of industrial gold mining, that meant billions of dollars in discarded metal — fragmented, occluded in mineral particles, beyond the reach of mechanically agitated cells.

Historical gold tailings are particularly rich because (i) residual grade, though low in relative terms, is still economically significant when processed with modern technology; (ii) many assets were operated before the era of column flotation and modern reagents, leaving greater upside; (iii) gold's density means that even at low concentration, recoverable mass per ton of tailings is substantial.

Green Mining angle

In the gold case, total cycle drops from ~114h to ~16h. Over 85% reduction.

It's the commodity where the combination of nano liberation (SLM), compact-column flotation, selective chemistry, and algorithmic control delivers the most expressive benchmark. Field-validated in South American operation since 2012, audited by SGS. Public recovery reaches up to 99% in gold in tailings with a favorable mineralogical profile, versus 60–75% for conventional flotation.
