sodium cyanide nacn gold flotation cell

The influence of cyanide on pyrite flotation from gold ...

1997-4-1  Sodium cyanide (NaCN) and sodium hydroxide (NaOH) were used to achieve the required cyanide concentration level and pH value respectively. The collector used was sodium isobutyl xanthate (SIBX) of 96% purity, obtained from SENM1N. It was stored in a desiccator with phosphorous pentoxide (P205) to limit atmospheric decomposition.
