Many common plants contain the natural form of cyanide, cyanic glucoside. Its presence may be the product of evolution, as it deters animals and insects from consuming the entire plant. Most animals can tolerate digesting small amounts, but during drought, the amont of the chemical in plants increases.

plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.

Insights to False Positive Total Cyanide Measurements in ...

The Cynoprobe offers the functionality to measure both 'free' and weak acid dissociable (WAD) cyanide concentration of up to three streams or sampling points. This results in a very cost-effective cyanide measurement solution. Cyanide reagent costs form a significant part of a gold plant's operating budget.
