INCO SO2 / Air Cyanide Detoxification Testing The destruction of cyanide compounds prior to discharge to your tailings storage facility is an important consideration in cyanide leaching. A number methods are available for this purpose and the most popular of these is the INCO SO 2 Air method.

Also, no mention is made to the main competition for the SO2/Air process, which is the hydrogen peroxide based methods. They're just as commonly used. DeGussa is one supplier of this technology. Someone should come up with a more definitive source, and the article should not plug only one specific cyanide destruction technology (NPOV).

There are a number of cyanide destruction process in use today. These include: Alkaline chlorination; Biological treatment; ... Sulfur dioxide and air. There are two patented versions of this process, held by Inco and Noranda, related to nickel processing. In particular, the mining operations use the process to treat tailing slurries.

Dec 09, 2013· Currently, the tailings are not desulphurized, but are treated for cyanide destruction using the INCO SO2/Air method prior to their disposal. As part of the companys tailings management program, a laboratory investigation was undertaken to examine the effectiveness of flotation in desulphurizing the tailings.

To reduce high cyanide concentration of the wastes, the used reagents in Inco's method include Na 2 S 2 O 5, CuSO 4 .5H 2 O and pressured by the air while Degussa method applied H .
