Abstract (en)
[origin: WO8808408A1] The invention relates to a method and system for separating by aeration a component, such as cyanide, from a liquid containing the component. The method comprises passing the liquid through an array of aeration columns arranged in stages so that the liquid flowing from one aeration column in a first stage is divided into two or more streams which are introduced into separate aeration columns in a successive second stage. The method also comprises passing air through the aeration columns counter-current to the liquid to entrain at least a portion of the component in the air thereby to separate at least the portion from the liquid.
