recovery technologies.

EnviroMetal Technologies Inc. is developing and commercializing economic and environmentally sustainable metal recovery technologies for applications in the primary and secondary metal industries. EnviroMetal extracts precious metals from ores, concentrates and E-Waste by deploying its proprietary non-cyanide, water-based and neutral pH treatment process.


Our Mission
To lower the environmental impact of gold mining and the treatment of recycled printed circuit board assemblies (PCBAs). To help our partners by providing an environmentally sustainable and financially competitive alternative to the extensive use of smelting, and the use of cyanide and mercury in gold mining.

Our unique and environmentally friendly technology

EnviroMetal’s proprietary and patented chemistry technology extracts precious and other valuable metals from conventional mine concentrates and printed circuit board assemblies.

Our unique technology is a cost-effective, environmentally sustainable and domestic alternative to the use of cyanide and smelters for the recovery of gold from primary and secondary sources.

Technology overview

The gold mining and E-Waste sectors both face monumental challenges to balance their economics and the environmental impact of their operations

EnviroMetal has the solution…

Our Value Proposition

To promote the broad adoption of our disruptive new technology to:

  • Reduce the environmental impact of gold mining,
  • Extract precious metals from end-of-life electronics and catalysts in a sustainable manner,
  • Lower the impact of gold production,
  • Unlock the value of smaller gold deposits,
  • Provide an environmentally friendly and sustainable alternative to the extensive use of smelters, mercury, and cyanide in mining,
  • Successfully deploy our in-situ gold recovery process (Group 11)

Envirometal is led by a first-class staff of scientists and engineers. Our extensive expertise in metals recovery and hydrometallurgy positions us with a unique knowledge set applicable to our target markets.

Our Technology Applications

Conventional Gold Mining

EnviroMetal offers a cost-effective and environmentally friendly alternative to the use of cyanide and smelting in the gold mining sector. It also offers a viable alternative to the smelting of gold concentrates. The company has completed thousands of tests on hundreds of different ores and concentrates with very positive results.

Recycled PCBAs

The recycling of precious metals from scrap printed circuit boards offers a tremendous opportunity to profit from the burgeoning recycling sectors. EnviroLeach offers the only domestic, cost-effective and sustainable solution for the recovery of the valuable metals contained in these products.

Pipeline Applications

Recycled Catalytic Converter

Borne out of extensive research and development spanning three years Envirometal continues to develop industry leading platinum and palladium recovery processes for the target application of recycled automotive catalytic converters. This is a global market opportunity with little or no competition other than conventional smelting.

In Situ Gold Recovery (ISR)

EnviroMetal has the potential to change the way the world extracts gold. With its partner Group 11 Technologies, EnviroMetal will be testing the potential for in-situ (or in-place) leaching of gold which would reduce the impact of gold mining around the globe. It offers the ability to extract gold without moving material or setting up conventional gold mills. EnviroMetal’s patented gold recovery chemistry and process applications make this opportunity possible.

Technological advantages

EnviroMetal has developed the most significant innovation in gold recovery since the introduction of cyanide in 150 years ago. The technology has been independently verified and has been rigorously tested on multiple concentrate materials.


Simple chemistry solution operates at ambient temperature and pressure.


Proprietary and patented core technology.


Low environmental footprint – produces no toxic air emissions or wastewater.


Efficient – excellent leach kinetics and recoveries.
