Cycladex Process

  • Quicker leach times 4h vs 36h
  • Higher recoveries typically 5%
  • Environmental concerns reduced
  • May work where gold is refractory (i.e. – those deposits where gold is trapped in minerals which can’t be leached by cyanide easily)
  • Lower cost, lower CAPEX

Cyanide Process

Cyanide revolutionized the recovery of gold from lower-grade and non-refractory deposits.

But it comes with its challenges

  • Additional costs (operating and capital)
  • Safety aspects in transport, storage and use
  • Community concerns
  • Not without its problems. e.g Baia Mare tailings spill in Romania
