Beschreibung
Zusammenfassung:	The invention relates to a method for measuring and adjusting electrochemical potential and/or component content in the process of treating valuable materials, when the valuable materials should be recovered either together or separately by aid of the values of the recovery range defined on the basis of electrochemical potential and component control. According to the invention, the measuring of electrochemical potential and/or component content is carried out by means of at least one electrode (4, 5), advantageously by means of a mineral electrode, so that in order to regulate the physicochemical state of the electrode and/or to remove the coating layer formed on the electrode surface and in order to protect the electrode, onto the electrode there is switched a supply voltage differing from the electrochemical balance potential of the electrode, which supply voltage is switched off before starting the measuring operation.
