Sodium cyanide. Sodium cyanide is mainly used to depress sphalerite in the first or lead-flotation stage in separating lead from zinc minerals. Its action on pyrite is nearly as strong as on sphalerite, but it does not affect galena unless a large excess is added or the contact time is too long. The effect of sodium cyanide is often intensified ...
