Gold Cyanide Leaching Process - Outotec

This makes cyanide detoxification a critical part of each cyanide leaching plant operation. Outotec offers several process options for cyanide detoxification in addition to natural degradation or solution dilution. Cyanide detoxification by the SO₂ /air process is commonly used, but the most efficient detoxification method is selected based on individual process requirements.

Destruction of Cyanide - ENVIOLET

Cyanide detoxification by chlorine is becoming increasingly disputed and often needs to be substituted for following reasons: 1.) The reactions of chlorine with organic substances like tensides or complexing agents lead to the formation of chlorinated organic compounds, detected as AOX (absorbable organic halogen), and lead to exceeding the limits of AOX.

2009-6-15 · Microbes may also use nitrilase activity for the detoxification and assimilation of nitriles and cyanide present in the plant environment. For example, the cyanide hydratase of the sorghum pathogen Gloeocercospora sorghi may allow this fungal pathogen to colonize its cyanogenic host plant (Wang and VanEtten, 1992; Wang et al., 1992). Sorghum plants store the cyanogenic glycoside dhurrin in

2013-8-2 · It was noted that slight difference existed in distribution of total cyanide in plant materials, but difference was not significant (p > 0.05). Cyanide recovered from roots accounted for 54.8 % (S.D. 1.64, n = 4) of the total cyanide detected in biomass of rice seedlings, whereas 45.2 % (S.D. 1.64, n = 4) was detected in shoots. Loss from control without plants was negligible; as a result, all losses were likely to

Cyanide contents were determined spectrophotometrically by incubation of cassava crude extracts with partially purified linamarase and measurement of the released cyanide by pyridine-pyrazolone and pyridine-barbiturate. The cortex of tuberous roots had total cyanide ranging from 180-720 µg/g fresh weight and 2-6 times higher than in the parenchyma.
