Tails. Tails. In the INCO process, free cyanide and weakly or moderately bound metal-cyanidt complexes present in the wastestream are oxidized to cyanate (CNO-) by the addition of sulfur dioxide and oxygen according to the following stoichiometric reaction: CN-w,(llb) + SO2(2.641b) + Oz(1.231b) + HZO.
- The difference between the efficiency and cost of the INCO process applied to a similar slurry and solution stream from the same site. - The effect of a high shear oxygen transfer device on the INCO process efficiency. - The implementation of automation on an existing INCO detox plant. 2.
