Conventional Gold Mining Sector

The EnviroLeach closed-loop process offers an almost zero environmental footprint. It offers excellent leach kinetics and recoveries. It operates at ambient temperature and pressure with no off-gassing or water effluent...

BENEFITS TO THE GOLD MINING SECTOR

The gold mining sector is currently dominated by cyanide as the leading gold extraction agent. It is an effective and low-cost reagent, 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. EnviroLeach’s chemistry formulations recover gold from gravity and floatation concentrates with similar effectiveness and costs to cyanide. 

 

EnviroLeach’s commercial strategy for the mining sector is based on a licensing and royalty model. EnviroLeach has little or no competition in the mining sector for economic, eco-friendly alternatives to cyanidation or smelting of gold concentrates. Our technical advantages and early mover status in this market positions us to become a dominant player. The EnviroLeach process offers the following benefits:

  • Environmentally safe & sustainable process

  • Comparable recovery of gold to cyanide

  • Comparable leach kinetics to cyanide 

  • Comparable economics to cyanide 

  • Comparable costs to smelting for concentrates

  • Operates at ambient temperature

  • Simplified permitting procedures

  • Operates at ambient pressure

  • Neutral pH based process

  • No water effluent produced

  • No tailings ponds necessary

  • Reduced water consumption 

  • Safer to handle and transport

  • Higher social acceptable level

  • Unlocks the value of smaller deposits

  • Access to environmentally sensitive areas
