Unfortunately, this activation process is not a very selective one. The activated collector can adsorb not only to the impurities but also to some of the clay particles which are consequently rendered hydrobophic and, therefore, prone to float as if they were impurities. This leads to losses of clay and inefficiencies in the flotation process.
