The next generation
of precious metal extraction technology


Easily extract Au, Ag, PGM metals from either rock ore materials or E-waste (electronic scrap metals, catalyst converters and solar panel) materials.

Easy to use and CUSTOMIZABLE to fit clients' operational capacities

No matter you are a hobbyist, small scale operator or a large mining company, we can always find a solution fitting your needs.
Eco-Goldex Agent can seamlessly replace cyanide in rock ore leaching process without change of existing flowsheet and equipment. The unique selective extraction feature of the agent makes it the best approach for precious metal stripping from e-waste materials.

Product Series

Eco-Goldex S-series

The S Series (it refers to Super agent) is specially formulated and manufactured with the purpose of replacing the toxic sodium cyanide in gold/silver/PGM rock ore leaching

Eco-Goldex E Series

For most large e-scrap recyclers, the most common solution of precious metal recovery is selling e-scrap materials to one of the few large smelters in the world

Unique Eco-Goldex Agent

Compared with Sodium Cyanide, Aqua Regia and other gold leaching chemicals applied in gold extraction,
Eco-Goldex product series has three unique features:

Selective Au/Ag/Pd Stripping

Eco-Goldex E product series has a unique feature that it can selectively strip precious metals (Au, Ag, Pd, Pt...) from plating electronic materials such as pins, connectors, RAM, CPU and PCB, while other metals like copper, nickel, aluminum are not or only slightly attacked.


Extraordinary High Stripping Efficiency and High Recovery Rate

Eco-goldex E product series has very powerful stripping efficiency in E-waste recycling in that gold stripping may take place within seconds to minutes (depending on the thickness of the plated gold) to complete gold stripping on PCB. Eco-Goldex's proprietary technology of electrowinning + Active Carbon (AC) adsorption method warrants over 99% gold recovery rate in E-scrap pregnant solution. Eco-Goldex claims that the extraordinary high stripping efficiency and gold recovery rate of Eco-goldex E agent making it stand out among its competitors in the market.

Low-toxicity and Simple Stripping/Recovery Processes

Eco-Goldex chemical agent is low-toxic. Eco-toxicology test results indicate that the Eco-Goldex product series is in the range of about 1-2% in toxicity of sodium cyanide.
In addition, both the Eco-Goldex O product series and the E series are simple processes in gold leaching/stripping.
The O product series shares the same leaching process and flowsheet as cyanidation. Eco-goldex O product series can replace cyanide in gold ore mine flowsheet (Heap leach, CIL/CIP) seamlessly without any circuit change or equipment modification.

The E series stripping/recovery process is as simple as step 1-2-3:
