Quartz crystal microbalance with dissipation (QCM-D) was used to study the zinc sulfide activation with silver, copper and lead. The interactions between calcium sulfate and minerals and gypsum nucleation on functional surfaces were investigated using a QCM-D, surface forces apparatus (SFA), and...
