suggest that HF plays an essential role in the process, and different possible mechanisms have been proposed [18]. This occurs because HF removes positively charged cations from the feldspar surface while depositing fluoride ions [15]. As a result of this mechanism, feldspar tends to be effectively depressed in the presence of collectors.
