Oxidize cyanide and thiocyanate in mine tailings and process wastewater within minutes. End months-long natural degradation.
The Problem
In gold mining, leaving cyanide wastewater to natural degradation in tailings ponds is the most common method — but it requires storing huge water volumes for a long time and carries continuous leakage/accident risk.
Natural degradation can take months, and risk persists throughout.
Safely storing huge water volumes for a long time requires extra infrastructure and cost.
A long storage period increases environmental accident and leakage risk.
Environmental audits on tailings management and cyanide discharge are increasingly tightening.
System Concept
OCS-MINE GUARD offers a four-stage architecture tailored to mine wastewater management.
Free and WAD cyanide and thiocyanate concentrations in tailings or process water are analyzed.
A kg/hour-scale, oxygen-fed ozone system is sized to the water volume.
A flow system that continuously draws and treats water from the tailings pond processes large volumes quickly.
Removal rate is documented via inlet/outlet analysis, approving safe discharge or backfill use.
Solution Areas
Cyanide oxidation in large-volume wastewater ponds.
Final treatment of plant outflow water before safe discharge.
Ozone-ice application that increases leach yield at low temperatures.
Pre-treating raw ore with ozone before leaching.
Technical Data
Why OCS-MINE GUARD?

Contribution to copper, zinc and nickel removal alongside cyanide.
A field-proven method researched since the 1950s.
Usable in tailings, process water, heap leaching and pre-oxidation.
Every project is sized for its cyanide and thiocyanate profile.
Application Sectors
Gold Mining · Silver Mining · Metal Plating Industry · Tailings Management Facilities
FAQ
Ozone first converts cyanide to less-toxic cyanate, then to bicarbonate and nitrogen — these end products can be safely discharged.
With a continuous-flow architecture, the system scales to continuously process large volumes; capacity is determined in the site analysis.
On the contrary, ozone-ice application at low temperatures can increase leach yield, especially in heap leaching.
Yes — it usually integrates into existing water-management infrastructure with no major structural change.
Cyanide and thiocyanate removal rates are verified with laboratory results via inlet/outlet analysis before and after commissioning.
