cyanide-containing waste

Large-scale treatment of a concentrated cyanide waste solution by acidification.

Mr. Elias wanted his workers to clean out a 25,000-gallon tank that contained cyanide waste.

Sodium hypochlorite solutions have been used to treat dilute cyanide waste water, such as electroplating wastes.

In batch treatment operations, sodium hypochlorite has been used to treat more concentrated cyanide wastes, such as silver cyanide plating solutions.

Cyanide wastes are generally treated using Chlorine or Sodium (or Calcium) Hypochlorite as the oxidising agent.

Ozone can be used to detoxify cyanide wastes (for example from gold and silver mining) by oxidising cyanide to cyanate and eventually to carbon dioxide.

Next he selects the Pollutant button and registers the word "carbon monoxide" found in the abstract Patent 2 The abstract describes the lowering of cyanide waste in manufacturing processes.

An AMIRA project on the environmental fate of cyanide, in and around tailings dams, has shown that under normal conditions, barring large accidental discharges, cyanide waste is unlikely to be dangerous.
