INCO SO2 / Air Cyanide Detoxification Testing
In a world of increasingly stringent legislation on cyanide levels in mining wastes the destruction of cyanide compounds prior to discharge to your tailings storage facility is becoming increasingly important.
A number methods are available for this purpose and the most popular of these is the INCO SO2 Air method due to its ability to reduce weakly acid dissociable cyanide (CNwad) contents effectively even when treating slurry.
Using this method, cyanide contents can be reduced down to below 5 mg/l using SO2 additions of between 3.5 and 4.5 g/g CNwad.
Grinding Solutions can test this process on laboratory test products or plant process slurries in batch and continuous modes to provide the most accurate indication of the reagent requirements to reach your goals.
