Precious Metal Extraction from Electronic Waste and Mines
OVERVIEW
Our innovation is a chemical solution that extracts precious metals at higher yields in shorter timeframes than conventional processes. It can also simultaneously extract multiple precious metals such as gold, silver and palladium.
This process can be applied to electronic waste or mining ore/tailings dams, significantly reducing processing time and environmental costs associated with minerals processing compared to current processes which use dangerously toxic chemicals such as cyanide and aqua regia.
OUR CAPABILITIES
Our process uses a chemical solution free of cyanide, mercury or aqua regia to extract precious metals. It can be adapted to process waste streams such as e-waste or mining ore - both which contain precious metals.
Non-Toxic Metal Extraction from Electronic Waste
The flowchart below shows the process by which we extract precious metals from e-waste (such as the circuit boards found in phones or computers).
This process can extract multiple precious metals simultaneously, without damaging the underlying hardware components (meaning they can also be recycled).
E-WASTE
(e.g. Mobile Phones)
Electronic components contain precious metals such as gold, silver and palladium. E-waste is growing exponentially around the world due to increasing electronic consumption.
CHEMICAL
PROCESS
Our solution is faster than conventional processes and extracts higher yields. Currently, most e-waste is processed using dangerous toxic chemicals such as cyanide and aqua-regia, ours is capable of metals extraction without any toxic chemicals.
PRECIOUS
METALS
Multiple precious metals can be extracted simultaneously, for sale on global commodity markets. Other hardware components remain undamaged and can be recycled for use in new electronic devices.

Metal Extraction from Mine Sites (e.g. Mine Tailings)
The flowchart below shows the process by which we can extract precious metals from mine sites. This can be applied to mine tailings or virgin ore, as our solution extracts at higher yields than industry standard.
We also save companies a significant amount in waste processing and environmental restoration costs that are associated with toxic chemicals like cyanide and aqua regia.
MINING MATERIAL
(e.g. Mine Tailings)
Mine tailings contain precious metals but are often deemed inefficient to process. Our solution can quickly extract higher yields of multiple precious metals simultaneously.
CHEMICAL
PROCESS
Our solution avoids the use of cyanide or aqua regia, meaning mining companies stand to save significantly on environmental restoration costs. Its also quicker with higher yields.

WHO WE WORK WITH
E-WASTE
COLLECTORS
Do you deal with commercial quantities of e-waste and are looking for a better processing option?
Contact us to learn about the opportunity to process e-waste locally, by using a non-toxic solution which maximises revenues from precious metals extraction and hardware component re-use.
ELECTRONIC
MANUFACTURERS
Are you a company that manufactures electronic products, looking to create an end-of-life option?
Contact us to learn about how you can benefit your bottom-line by reclaiming precious metals and hardware components to be re-purposed into new electronic devices.
MINING COMPANIES
Are you a mining company wanting to extract higher yields from ores or tailings material and minimise environmental costs?
Contact us to learn about how we can collaboratively develop a solution to increase your extraction efficiency using our chemical solution, or extract from tailings currently deemed un-economical to process.
