Gold Cyanidation Process. A titration is simply a method of determining the amount of reagent in the slurry. There are chemicals that will react to each of these two reagents in a predetermined manner. By measuring the amount of chemical that is used to obtain that reaction it is possible to determine the amount of reagent that is in the slurry.
