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
