Environmental Opportunities in the Gold Mining and Urban Mining Sectors

  • 66,000 tonnes of Cyanide is used annually in mining
  • 1,400 tonnes of Mercury is used annually in mining
  • Mine operators under pressure for environmental change
  • 50,000,000 tonnes of E-Waste is generated annually and growing
  • $62 Billion USD in precious metals is used in electronics annually
  • No eco-friendly & sustainable solution for recycling E-Waste
