CORE TECHNOLOGY APPLICATIONS
Cyanide is the leading gold extraction agent. It is effective and low cost, but it is a toxic chemical that creates significant environmental risk for mine operators and local communities. It is increasingly opposed by many communities, NGO’s, governments, agencies and investors.
Other miners produce gold concentrates that are shipped to smelters for processing. Payment times are lengthy, shipping and logistics costs are considerable, processing costs are high.
Environmental and carbon footprint of both existing processes are high.
EnviroMetal’s chemistry formulations recover gold from gravity and flotation concentrates with similar effectiveness and costs to cyanide. We allow concentrate producers to recover gold doré on site. We help gold producers reduce processing costs and environmental footprints in many cases.

Gold Mining Business Model
EnviroMetal has little or no competition in the mining sector for economic, sustainable alternatives to cyanide.
We also offer significant value to gold miners who produce concentrate materials, but who would prefer to recover gold on-site rather than incur costs for downstream processing. Our technical advantages and early mover status in this market position us as to be a dominant player.
EnviroMetal’s gold sector strategy is based on a licensing and royalty model.
EnviroMetal offers a cost-effective, sustainable, domestic solution for the treatment of printed circuit boards. EnviroMetal is also developing hydrometallurgical recovery applications for tin and copper, which present the potential for significantly increased operating margins. Our solution integrates with ESG multiple principles and provides a valuable solution for the adoption of Circular Economy for metals and electronics industries.
