Gold Leaching Agitation Tanks
In cyanidation leaching work, however, it is evident that agitation has two purposes only: to keep the solids in suspension while dissolution is taking place and; to supply the required amount of oxygen. Violent agitation has no recognised value in itself, but ample oxygen supply is essential to promote the reaction between gold, silver, and cyanide.
